Protein Classification

tetraspanin family protein( domain architecture ID 548)

tetraspanin family protein is a transmembrane (TM) glycoprotein with four TM segments that facilitates the interaction of membrane and intracellular signaling molecules (such as integrins, pro-growth factors and their receptors, protein kinase-C) in the formation of membrane signaling microdomains (also referred to as the tetraspanin web)

 24-107 3.60e-39

Tetraspanin, extracellular domain or large extracellular loop (LEL). Tetraspanins are trans-membrane proteins with 4 trans-membrane segments. Both the N- and C-termini lie on the intracellular side of the membrane. This alignment model spans the extracellular domain between the 3rd and 4th trans-membrane segment. The tetraspanin family contains CD9, CD63, CD37, CD53, CD82, CD151, and CD81, amongst others. Tetraspanins are involved in diverse processes such as cell activation and proliferation, adhesion and motility, differentiation, cancer, and others. Their various functions may relate to their ability to act as molecular facilitators, grouping specific cell-surface proteins and affecting formation and stability of signaling complexes. Tetraspanins associate laterally with one another and cluster dynamically with numerous parnter domains in membrane microdomains, forming a network of multimolecular complexes, the "tetraspanin web", which may also include integrins.

Uroplakin Ia and Ib are components of the 16nm protein particles, which are packed hexagonally to form 2D crystals of asymmetric unit membranes, and cover the apical surface of mammalian urothelium, contributing to the urinay bladder's permeability barrier function. Uroplakins Ia and Ib are maturation facilitators. They trigger conformational changes in their single-transmembrane-domain binding partner proteins uroplakin II and IIIa, which in turn may lead to ER-exit, stabilization, and cell-surface expression.

CD151strongly associates with integrins, especially alpha3beta1, alpha6beta1, alpha7beta1, and alpha6beta4; it may play roles in cell-cell adhesion, cell migration, platelet aggregation, and angiogenesis. For example, CD151 is is involved in regulation of migration of neutrophils, endothelial cells, and various tumor cell lines; it associates specifically with laminin-binding integrins and strengthens alpha6beta1 integrin-mediated adhesion to laminin-1; CD151 also specifically attenuates adhesion-dependent activation of Ras and correspdonding downstream effects, and is involved in epithelial cell-cell adhesion as a modulator of PKC- and Cdc42-dependent actin cytoskeletal reorganization.

Tetraspanin, extracellular domain or large extracellular loop (LEL), peripherin_like family. Tetraspanins are trans-membrane proteins with 4 trans-membrane segments. Both the N- and C-termini lie on the intracellular side of the membrane. This alignment model spans the extracellular domain between the 3rd and 4th trans-membrane segment. Tetraspanins are involved in diverse processes and their various functions may relate to their ability to act as molecular facilitators. Tetraspanins associate laterally with one another and cluster dynamically with numerous parnter domains in membrane microdomains, forming a network of multimolecular complexes, the "tetraspanin web". Peripherin, or RDS (retinal degradation slow) is a glycoprotein expressed in vertebrate photoreceptors, located at the rim of the disc membranes of the photoreceptor outer segments. RDS is thought to play a major role in folding and stacking of the discs. Mutations in RDS have been linked to hereditary retinal dystrophies, which typically exhibit a wide phenotypic spectrum.

Tetraspanin, extracellular domain or large extracellular loop (LEL), TM4SF3_like subfamily. Tetraspanins are trans-membrane proteins with 4 trans-membrane segments. Both the N- and C-termini lie on the intracellular side of the membrane. This alignment model spans the extracellular domain between the 3rd and 4th trans-membrane segment. Tetraspanins are involved in diverse processes and their various functions may relate to their ability to act as molecular facilitators. Tetraspanins associate laterally with one another and cluster dynamically with numerous parnter domains in membrane microdomains, forming a network of multimolecular complexes, the "tetraspanin web". This subfamily contaions transmembrane 4 superfamily 3 (TM4SF3) or D6.1a and related proteins. D6.1a associates with alpha6beta4 integrin and supports cell motility, it has been ascribed a role in tumor progression and metastasis.

Tetraspanin, extracellular domain or large extracellular loop (LEL), CD37_CD82_Like family. Tetraspanins are trans-membrane proteins with 4 trans-membrane segments.

Tetraspanins are involved in diverse processes and their various functions may relate to their ability to act as molecular facilitators. Tetraspanins associate laterally with one another and cluster dynamically with numerous parnter domains in membrane microdomains, forming a network of multimolecular complexes, the "tetraspanin web". CD37 is a leukocyte-specific protein, and its restricted expression pattern suggests a role in the immune system. A regulatory role in T-cell proliferation has been suggested. CD82 is a metastasis suppressor implicated in biological processes ranging from fusion, adhesion, and migration to apoptosis and alterations of cell morphology.

This subfamily contaions transmembrane 4 superfamily 9 (TM4SF9) or Tetraspanin-5 and related proteins. TM4SF9 is strongly expressed witin the central nervous system, and expression levels appear to correlate with differentiation status of particular neurons, hinting at a role in neuronal maturation.
