background:
May act as an adapter protein to couple membrane receptors to intracellular signaling pathways. May be involved in signaling of ITGB2/LFA-1 and other integrins. Enhances HGF-MET signaling by recruiting Sos and activating the Ras pathway. Involved in activation of androgen and glucocorticoid receptor in the presence of their cognate hormones. Stabilizes TP73 isoform Alpha, probably by inhibiting its ubiquitination, and increases its proapoptotic activity. Inhibits the kinase activity of DYRK1A and DYRK1B. Inhibits FMR1 binding to RNA.
Tissue specificity: Ubiquitously expressed, with highest levels in testes, placenta, heart, and muscle, and lowest levels in lung. Within the brain, expressed predominantly by neurons in the gray matter of cortex, the granular layer of cerebellum and the Purkinje cells.
Function:
May act as an adapter protein to couple membrane receptors to intracellular signaling pathways. May be involved in signaling of ITGB2/LFA-1 and other integrins. Enhances HGF-MET signaling by recruiting Sos and activating the Ras pathway. Enhances dihydrotestosterone-induced transactivation activity of AR, as well as dexamethasone-induced transactivation activity of NR3C1, but not affect estrogen-induced transactivation. Stabilizes TP73 isoform Alpha, probably by inhibiting its ubiquitination, and increases its proapoptotic activity. Inhibits the kinase activity of DYRK1A and DYRK1B. Inhibits FMR1 binding to RNA (By similarity).
Subunit:
Interacts with NGFR and DDX4 (By similarity). Interacts with GTP-bound Ran, AR, CDC2L1/p110C, CALB1, S100A7, USP11, MKLN1, SOS1 or SOS2, GID8, and FMR1. Interacts with the Dyrk kinases HIPK2, DYRK1A, and DYRK1B. Interacts with TP73 isoform Alpha but not with TP53. Interacts with the HGF receptor MET and the integrins ITGB1 and ITGB2, but not with ITGAL. Part of a complex consisting of RANBP9, MKLN1 and GID8. Part of a complex consisting of RANBP9, RAN, DYRK1B and COPS5. Directly interacts with RANBP10.
Subcellular Location:
Cytoplasm, cytosol. Nucleus. Note==Predominantly cytoplasmic. A phosphorylated form is associated with the plasma membrane.
Tissue Specificity:
Ubiquitously expressed, with highest levels in testes, placenta, heart, and muscle, and lowest levels in lung. Within the brain, expressed predominantly by neurons in the gray matter of cortex, the granular layer of cerebellum and the Purkinje cells.
Post-translational modifications:
Phosphorylated in response to stress. Can be phosphorylated by the cleaved p110 form of CDC2L1 (p110C). [PTM] Ubiquitinated. Polyubiquitination targets the protein for rapid degradation via the ubiquitin system. Can be deubiquitinated by USP11.
Similarity:
Belongs to the RANBP9/10 family.
Contains 1 B30.2/SPRY domain.
Contains 1 CTLH domain.
Contains 1 LisH domain.
