    basic FUNCTION
  • functioning as an effector or regulator of RAS
  • regulates endocytosis of the EPHA4 receptor in mature excitatory neurons (Deininger 2008)
  • play an important role in the endocytosis of the epidermal growth factor receptor (EGFR)
  • regulates EGFR degradation in cooperation with STAM, defining a novel role for Rin1 in regulating endosomal trafficking
  • serves as an important signal transduction system for evaluating the malignancy of colorectal cancer
  • RAS effector regulating epithelial cell properties
  • acting as a negative regulator of tumor cell invasive growth and that this requires the ABL kinase-signaling function of RIN1, suggesting a mechanism through which RIN1 silencing may contribute to breast cancer progression
  • selective association of RAB5A and RIN1 contributes to the dominance of RAB5A in EGFR trafficking, whereas RAB5B, RAB5C may have major functions unrelated to the EGFR degradation pathway
  • RAS effector protein involved in the regulation of epithelial cell processes such as cell migration and endocytosis
  • growth factor-directed cell migration, a physiological process that involves receptor endocytosis and actin remodeling, also requires the ability of RIN1 to coordinate RAB5 GTPase and ABL tyrosine kinase pathways
  • is a host cell regulator that performs counterbalancing functions during early and late stages of L. monocytogenes infection
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
  • novel PRKD1 signaling pathway through RIN1 and Abl kinases that is involved in the regulation of actin remodeling and cell migration
  • a component
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • 14.3.3 proteins and proteins containing SH3 domain
  • interacts with signal-transducing adaptor molecule 2 (STAM2), a protein that associates with hepatocyte growth factor-regulated substrate and plays a key role in the endosomal sorting machinery
  • RIN1, RIN2, RIN3 serve as guanine nucleotide exchange factors for RAB5A
  • RIN1 directly activates ABL tyrosine kinases, which regulate actin remodeling, a function not previously connected to endocytosis
  • EGFR activation also promotes RIN1 interaction with BIN1, a membrane bending protein
  • MFN2 and RIN1 are new SMAD2 binding partners required for mitochondrial fusion
