Hepatocyte growth factor-regulated tyrosine kinase substrate (HGS)

Involved in intracellular signal transduction mediated by cytokines and growth factors. When associated with STAM, it suppresses DNA indicating upon stimulation by IL-2 and GM-CSF.

Could be a direct effector of PI3-kinase in vesicular pathway via early endosomes and may regulate trafficking to early and late endosomes by recruiting clathrin. May focus ubiquitinated receptors in clathrin-coated regions.
