- 货号：KA3453C
- 应用：ELISA
- 种属：Human;Mouse;Rat
- 其他名称：
- Hepatocyte growth factor-regulated tyrosine kinase substrate (Hrs) (Protein pp110)
- 背景：
- domain:Has a double-sided UIM that can bind 2 ubiquitin molecules, one on each side of the helix.,function:Involved in intracellular signal transduction mediated by cytokines and growth factors. When associated with STAM, it suppresses DNA signaling 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 concentrate ubiquitinated receptors within clathrin-coated regions. Involved in down-regulation of receptor tyrosine kinase via multivesicular body (MVBs) when complexed with STAM (ESCRT-0 complex). The ESCRT-0 complex binds ubiquitin and acts as sorting machinery that recognizes ubiquitinated receptors and transfers them to further sequential lysosomal sorting/trafficking processes. May contribute to the efficient recruitment of SMADs to the activin receptor complex.,PTM:Phosphorylated on Tyr-334. A minor site of phosphorylation on Tyr-329 is detected (By similarity). Phosphorylation occurs in response to EGF, IL-2, GM-CSF and HGF.,similarity:Contains 1 FYVE-type zinc finger.,similarity:Contains 1 UIM (ubiquitin-interacting motif) repeat.,similarity:Contains 1 VHS domain.,subunit:Component of the ESCRT-0 complex composed of STAM or STAM2 and HGS. Part of a complex at least composed of HSG, STAM2 (or probably STAM) and EPS15. Interacts with STAM. Interacts with STAM2. Interacts with EPS15; the interaction is direct, calcium-dependent and inhibited by SNAP25. Interacts with NF2; the interaction is direct. Interacts with ubiquitin; the interaction is direct. Interacts with VPS37C. Interacts with SMAD1, SMAD2 and SMAD3. Interacts with TSG101; the interaction mediates the association with the ESCRT-I complex. Interacts with SNAP25; the interaction is direct and decreases with addition of increasing concentrations of free calcium. Interacts with SNX1; the interaction is direct. Component of a 550 kDa membrane complex at least composed of HGS and SNX1 but excluding EGFR.,tissue specificity:Ubiquitous expression in adult and fetal tissues with higher expression in testis and peripheral blood leukocytes.,
