Description
Description
Tetraspanins (TSP) have four transmembrane domains and two extracellular loops containing specific short motifs, including highly conserved cysteine residues. TSPs are thought to function as scaffolds that bring multiple proteins - including other TSPs, membrane-associated proteins, extracellular and cytosolic proteins - into single membrane region. These regions are called tetraspanin-enriched microdomains. (Adapted from FBrf0227776 and FBrf0152316).
Notes on Group
CG30160 is included in the TETRASPANINS gene group as it is a tandem duplicate of Tsp42Eb (FBrf0206967) and is identical within the coding region.
In FBrf0132356, CG31600 is reported as a Tetraspanin, although its sequence is highly divergent to other members, it possesses a four predicted transmembrane regions and is therefore tentatively included in the TETRASPANINS gene group.
