    Summary
    This gene encodes a member of the integrin alpha chain family of proteins. The encoded preproprotein is proteolytically processed to generate light and heavy chains that associate through disulfide linkages to form a subunit of the alpha-IIb/beta-3 integrin cell adhesion receptor. This receptor plays a crucial role in the blood coagulation system, by mediating platelet aggregation. Mutations in this gene are associated with platelet-type bleeding disorders, which are characterized by a failure of platelet aggregation, including Glanzmann thrombasthenia.

    • Signalling by NGF, organism-specific biosystem (from REACTOME)
      Signalling by NGF, organism-specific biosystemNeurotrophins (NGF, BDNF, NT-3, NT-4/5) play pivotal roles in survival, differentiation, and plasticity of neurons in the peripheral and central nervous system. They are produced, and secreted in mi...
    • Signalling to ERKs, organism-specific biosystem (from REACTOME)
      Signalling to ERKs, organism-specific biosystemNeurotrophins utilize multiple pathways to activate ERKs (ERK1 and ERK2), a subgroup of the large MAP kinase (MAPK) family, from the plasma membrane. The major signalling pathways to ERKs are via RAS...
    • Signalling to RAS, organism-specific biosystem (from REACTOME)
      Signalling to RAS, organism-specific biosystemSignalling through Shc adaptor proteins appears to be identical for both NGF and EGF. It leads to a fast, but transient, MAPK/ERK activation, which is insufficient to explain the prolonged activation...
    • Signalling to p38 via RIT and RIN, organism-specific biosystem (from REACTOME)
      Signalling to p38 via RIT and RIN, organism-specific biosystemRIT and RIN are two small guanine nucleotide binding proteins that share more than 50% sequence identity with RAS, including highly conserved core effector domains. Unlike RAS, the C termini of RIT a...
    • Small cell lung cancer, organism-specific biosystem (from KEGG)
      Small cell lung cancer, organism-specific biosystemLung cancer is a leading cause of cancer death among men and women in industrialized countries. Small cell lung carcinoma (SCLC) is a highly aggressive neoplasm, which accounts for approximately 25% ...

    • VEGFA-VEGFR2 Pathway, organism-specific biosystem (from REACTOME)
      VEGFA-VEGFR2 Pathway, organism-specific biosystemAngiogenesis is the formation of new blood vessels from preexisting vasculature. One of the most important proangiogenic factors is vascular endothelial growth factor (VEGF). VEGF exerts its biologic...
    • VEGFR2 mediated cell proliferation, organism-specific biosystem (from REACTOME)
      VEGFR2 mediated cell proliferation, organism-specific biosystemVEGFR2 stimulates ERK not via GRB2-SOS-RAS, but via pY1175-dependent phosphorylation of PLC gamma and subsequent activation of PKCs. PKC plays an important mediatory role in the proliferative Ras/Raf...
    • p130Cas linkage to MAPK signaling for integrins, organism-specific biosystem (from REACTOME)
      p130Cas linkage to MAPK signaling for integrins, organism-specific biosystemIntegrin signaling is linked to the MAP kinase pathway by recruiting p130cas and Crk to the FAK/Src activation complex.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
