CAP-Gly domain; Cytoskeleton-associated proteins (CAPs) are involved in the organization of microtubules and transportation of vesicles and organelles along the cytoskeletal network. A conserved motif, CAP-Gly, has been identified in a number of CAPs, including CLIP-170 and dynactins. The crystal structure of Caenorhabditis elegans F53F4.3 protein CAP-Gly domain was recently solved. The domain contains three beta-strands. The most conserved sequence, GKNDG, is located in two consecutive sharp turns on the surface, forming the entrance to a groove.

 13-92 1.18e-33

ubiquitin-like (Ubl) domain found in tubulin-folding cofactor B (TBCB) and similar proteins; TBCB, also termed cytoskeleton-associated protein 1, or cytoskeleton-associated protein CKAPI, or tubulin-specific chaperone B, is one of protein cofactors A through E that is required for the folding of tubulins prior to their incorporation into microtubules and heterodimer assembly. TBCB comprises an N-terminal ubiquitin-like (Ubl) domain and a C-terminal cytoskeleton-associated protein with glycine-rich segment (CAP-Gly) domain. The Ubl domain of TBCB is essential for proper folding and assembly of tubulin alpha. It has a beta-grasp Ubl fold, a common structure involved in protein-protein interactions. Ubiquitin (Ub) is a protein modifier in eukaryotes that is involved in various cellular processes, including transcriptional regulation, cell cycle control, and DNA repair. TBC-A through E are necessary for the biogenesis of microtubules and for cell viability.

 15-91 5.43e-04

ubiquitin-like (Ubl) domain found in ubiquitin and ubiquitin-like Ubl proteins; Ubiquitin-like (Ubl) proteins have a similar ubiquitin (Ub) beta-grasp fold and attach to other proteins in a Ubl manner but with biochemically distinct roles. Ub and Ubl proteins conjugate and deconjugate via ligases and peptidases to covalently modify target polypeptides. Some Ubl domains have adaptor roles in Ub-signaling by mediating protein-protein interaction. Prokaryotic sulfur carrier proteins are Ub-related proteins that can be activated in an ATP-dependent manner. Polyubiquitination signals for a diverse set of cellular events via different isopeptide linkages formed between the C terminus of one ubiquitin (Ub) and the epsilon-amine of K6, K11, K27, K29, K33, K48, or K63 of a second Ub. One of these seven lysine residues (K27, Ub numbering) is conserved in this Ubl_ubiquitin_like family. K27-linked Ub chains are versatile and can be recognized by several downstream receptor proteins. K27 has roles beyond chain linkage, such as in Ubl NEDD8 (which contains many of the same lysines (K6, K11, K27, K33, K48) as Ub) where K27 has a role (other than conjugation) in the mechanism of protein neddylation.

 30-90 2.12e-03

ubiquitin-like (Ubl) domain found in tubulin-folding cofactor E (TBCE) and similar proteins; TBCE, also termed tubulin-specific chaperone E, is a tubulin polymerizing protein involved in the second step of the tubulin folding pathway through cooperating in tubulin heterodimer dissociation both in vivo and in vitro. It may also be implicated in the maintenance of the neuronal microtubule network. Mutations in TBCE gene cause hypoparathyroidism, mental retardation and facial dysmorphism. TBCE contains an N-terminal cytoskeleton-associated protein with glycine-rich segment (CAP-Gly) domain, a leucine-rich repeat protein-protein interaction domain followed by leucine-rich repeat (LRR) domains, and a C-terminal ubiquitin-like (Ubl) domain. Ubiquitin is a protein modifier in eukaryotes that is involved in various cellular processes.
