|Description: KH domain-containing, RNA-binding, signal transduction-associatedprotein 1 (p21 Ras GTPase-activating protein-associated p62) (GAP-associated tyrosine phosphoprotein p62) (Src-associated in mitosis 68kDa protein) (Sam68) (p68).|
UniprotKB/SwissProt: KHDR1_HUMAN (Q07666)
Function: Recruited and tyrosine phosphorylated by several receptor systems, for example the T-cell, leptin and insulin receptors. Once phosphorylated, functions as an adapter protein in signal transduction cascades by binding to SH2 and SH3 domain- containing proteins. Role in G2-M progression in the cell cycle. Represses CBP-dependent transcriptional activation apparently by competing with other nuclear factors for binding to CBP. Also acts as a putative regulator of mRNA stability and/or translation rates and mediates mRNA nuclear export. Isoform 3, which is expressed in growth-arrested cells only, inhibits S phase.
