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 a 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. Involved in receptor recycling via its association with the CART complex, a multiprotein complex required for efficient transferrin receptor recycling but not for EGFR degradation.

The HGS protein also known as hepatocyte growth factor-regulated tyrosine kinase substrate plays a significant role in cellular processes. It has a molecular mass of approximately 82 kDa. You will find HGS expressed broadly especially in epithelial tissues where it contributes to regulating various cellular mechanisms. Alternative names for HGS include HRS and HGS products which reflect its involvement in various signaling pathways and functions.
The HGS acts as a central player in endosomal sorting and targeting processes. It forms a part of the ESCRT-0 complex important for the degradation of surface receptors as it directs ubiquitinated membrane proteins to lysosomes for degradation. HGS interacts with other proteins in the complex such as STAM (Signal transducing adaptor molecule). This role explains its importance in maintaining proper cellular signaling and balance.
The HGS protein participates in the endocytosis and ubiquitin-proteasome pathways. HGS plays a critical role in the degradation of epidermal growth factor receptor (EGFR) by assisting its trafficking to lysosomes. This function ties it to cellular communication and signal transduction particularly related to growth signals. Within these pathways HGS closely interacts with proteins such as the hepatocyte growth factor (HGF) and c-Met playing a regulatory role in signal attenuation.
Aberrations in the HGS function link to cancer and neurodegenerative disorders. Dysregulation of the HGS-mediated pathways can lead to abnormal cell growth and cancer progression particularly in epithelial tissues. Additionally research indicates a connection between HGS dysfunction and Alzheimer's disease as it may influence amyloid-beta processing. Interactions with proteins like EGFR and c-Met suggest that alterations in the HGS activity could have significant implications for disease pathogenesis and progression.

ESCRT complexes participate in sequestration of mitochondria.(a) Confocal maximal image projections of Atg5−/− MEFs infected with mCherry-Parkin and treated with DMSO or 25 μM FCCP for the indicated time. Cells were stained with anti-Tim23 or anti-Tom20 (white) to label mitochondria, and for the indicated ESCRT protein (green). Enlarged boxes are single optical slices with arrowheads showing co-localization. Scale bars, 20 μm.
