The second LIM domain of Testin-like family; The second LIM domain of Testin-like family: This family includes testin, prickle, dyxin and LIMPETin. Structurally, testin and prickle proteins contain three LIM domains at C-terminal; LIMPETin has six LIM domains; and dyxin presents only two LIM domains. However, all members of the family contain a PET protein-protein interaction domain. Testin is a cytoskeleton associated focal adhesion protein that localizes along actin stress fibers, at cell-cell-contact areas, and at focal adhesion plaques. Testin interacts with a variety of cytoskeletal proteins, including zyxin, mena, VASP, talin, and actin and it is involved in cell motility and adhesion events. Prickles have been implicated in roles of regulating tissue polarity or planar cell polarity (PCP). Dyxin involves in lung and heart development by interaction with GATA6 and blocking GATA6 activated target genes. LIMPETin might be the recombinant product of genes coding testin and four and half LIM proteins and its function is not well understood. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

LIMPETin is an exception, containing six LIM domains. FHL1, 2 and 3 are predominantly expressed in muscle tissues, and FHL5 is highly expressed in male germ cells. FHL proteins exert their roles as transcription co-activators or co-repressors through a wide array of interaction partners. For example, FHL1 binds to Myosin-binding protein C, regulating myosin filament formation and sarcomere assembly. FHL2 has shown to interact with more than 50 different proteins, including receptors, structural proteins, transcription factors and cofactors, signal transducers, splicing factors, DNA replication and repair enzymes, and metabolic enzymes. FHL3 int eracts with many transcription factors, such as CREB, BKLF/KLF3, CtBP2, MyoD, and MZF_1. FHL5 is a tissue-specific coactivator of CREB/CREM family transcription factors.

The sixth LIM domain of protein LIMPETin; The sixth LIM domain of protein LIMPETin: LIMPETin contains 6 LIM domains at the C-terminal and an N-terminal PET domain. Four of the six LIM domains are highly homologous to the four and half LIM domain protein family and two of them show sequence similarity to the LIM domains of the testin family. Thus, LIMPETin may be the recombinant product of genes coding testin and FHL proteins. In Schistosoma mansoni, where LIMPETin was first identified, LIMPETin is down regulated in sexually mature adult Schistosoma females compared to sexually immature adult females and adult male. Its differential expression indicates that it is a transcription regulator. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The third LIM domain of the paxillin like protein family; The third LIM domain of the paxillin like protein family: This family consists of paxillin, leupaxin, Hic-5 (ARA55), and other related proteins. There are four LIM domains in the C-terminal of the proteins and leucine-rich LD-motifs in the N-terminal region. Members of this family are adaptor proteins to recruit key components of signal-transduction machinery to specific sub-cellular locations. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. Paxillin serves as a platform for the recruitment of numerous regulatory and structural proteins that together control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression that are necessary for cell migration and survival. Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. It associates with focal adhesion kinases PYK2 and pp125FAK and identified to be a component of the osteoclast pososomal signaling complex. Hic-5 controls cell proliferation, migration and senescence by functioning as coactivator for steroid receptors such as androgen receptor, glucocorticoid receptor and progesterone receptor. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The first LIM domain of Zyxin; The first LIM domain of Zyxin: Zyxin exhibits three copies of the LIM domain, an extensive proline-rich domain and a nuclear export signal. Localized at sites of cell substratum adhesion in fibroblasts, Zyxin interacts with alpha-actinin, members of the cysteine-rich protein (CRP) family, proteins that display Src homology 3 (SH3) domains and Ena/VASP family members. Zyxin and its partners have been implicated in the spatial control of actin filament assembly as well as in pathways important for cell differentiation. In addition to its functions at focal adhesion plaques, recent work has shown that zyxin moves from the sites of cell contacts to the nucleus, where it directly participates in the regulation of gene expression. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein.

The sixth LIM domain of protein LIMPETin; The sixth LIM domain of protein LIMPETin: LIMPETin contains 6 LIM domains at the C-terminal and an N-terminal PET domain. Four of the six LIM domains are highly homologous to the four and half LIM domain protein family and two of them show sequence similarity to the LIM domains of the testin family. Thus, LIMPETin may be the recombinant product of genes coding testin and FHL proteins. In Schistosoma mansoni, where LIMPETin was first identified, LIMPETin is down regulated in sexually mature adult Schistosoma females compared to sexually immature adult females and adult male. Its differential expression indicates that it is a transcription regulator. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

FHL3 was also proved to possess the auto-activation ability and was confirmed that the second zinc finger motif in fourth LIM domain was responsible for the auto-activation of FHL3.

The first LIM domain of the paxillin like protein family; The first LIM domain of the paxillin like protein family: This family consists of paxillin, leupaxin, Hic-5 (ARA55), and other related proteins. There are four LIM domains in the C-terminal of the proteins and leucine-rich LD-motifs in the N-terminal region. Members of this family are adaptor proteins to recruit key components of signal-transduction machinery to specific sub-cellular locations. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. Paxillin serves as a platform for the recruitment of numerous regulatory and structural proteins that together control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression that are necessary for cell migration and survival. Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. It associates with focal adhesion kinases PYK2 and pp125FAK and identified to be a component of the osteoclast pososomal signaling complex. Hic-5 controls cell proliferation, migration and senescence by functioning as coactivator for steroid receptors such as androgen receptor, glucocorticoid receptor and progesterone receptor. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.
