Also known as STAM1; STAM-1
Summary This gene encodes a member of the signal-transducing adaptor molecule family. These proteins mediate downstream signaling of cytokine receptors and also play a role in ER to Golgi trafficking by interacting with the coat protein II complex. The encoded protein also associates with hepatocyte growth factor-regulated substrate (HRS) to form the endosomal sorting complex required for transport-0 (ESCRT-0), which sorts ubiquitinated membrane proteins to the ESCRT-1 complex for lysosomal degradation. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Feb 2011]
Expression Ubiquitous expression in bone marrow (RPKM 13.8), brain (RPKM 7.5) and 25 other tissues See more Orthologs mouse all

 ( Vps27 rekrytoi seuraavan kompleksi ESCRT-1).

 Model for compartment specification of Ub-dependent sorting into MVB vesicles. The Vps15/Vps34 complex synthesizes PI(3)P on endosomal membranes. The class E Vps protein Vps27 is targeted to PI(3)P- containing endosomal membranes via its FYVE domain (dark blue) where it can bind ubiquitinated MVB cargo via its UIM motifs (yellow). Vps27 subsequently recruits/activates ESCRT-I (orange) on endosomes. Ubiquitinated cargo (such as pCPS) is recognized by ESCRT-I (via the Ub E2 variant domain of Vps23), which initiates cargo entry into MVB vesicles. The action of a number of additional class E Vps proteins (ESCRT-II and ESCRT-III) is required for not only the function of this pathway but also for recruiting the deubiquitinating enzyme to remove Ub from cargo before its entry into invaginating vesicles. The concerted action of these proteins results in the sorting of cargo into the MVB pathway.
