Protein Domain : STAM2, SH3 domain IPR035675

Type	Domain
Description	This entry represents the SH3 domain of STAM2 (signal transducing adapter molecule 2). STAM2, a subunit of the ESCRT-0 complex, is an endosomal protein acting as a regulator of receptor signaling and trafficking. It contains an N-terminal VHS domain (Vps-27/Hrs/Stam), UIM (ubiquitin-interacting motif), SH3 (Src homology 3), CC ("coiled coil"), SSM (STAM-specific motif) and C-terminal ITAM (immunoreceptor tyrosine-based activation motif) domain. It may play a regulatory role in the endosomal sorting of ubiquitinated membrane proteins [ ]. STAMs were discovered as proteins that are highly phosphorylated following cytokine and growth factor stimulation [ ]. They function in cytokine signaling and surface receptor degradation, as well as regulate Golgi morphology. They associate with many proteins including Jak2 and Jak3 tyrosine kinases [], Hrs, AMSH, and UBPY. STAM adaptor proteins contain VHS (Vps27, Hrs, STAM homology), ubiquitin interacting (UIM), and SH3 domains [].
