Background Information

KHDRBS1, also named as SAM68, p62and p68, belongs to the KHDRBS family. It is recruited and tyrosine phosphorylated by several receptor systems, for example the T-cell, leptin and INS receptors. Once phosphorylated, KHDRBS1 functions as an adapter protein in signal transduction cascades by binding to SH2 and SH3 domain-containing proteins. It represses CBP-dependent transcriptional activation apparently by competing with other nuclear factors for binding to CBP. KHDRBS1 also acts as a putative regulator of mRNA stability and/or translation rates and mediates mRNA nuclear export. KHDRBS1 has three isoforms with calculated MW of 44-48kd. For isoform with a calculated MW of 48.2 kD, it migrated as a 68kD protein on SDS-PAGE gels[PMID: 10564820]. This ia a rabbit polyclonal antibody raised against residues near the N terminus of human KHDRBS1.
