Rabbit anti-Human KHDRBS3 Polyclonal Antibody

Uniprot Id

O75525

Target Species

Human

Target Name

KHDRBS3

Target Full Name

KH domain-containing, RNA-binding, signal transduction-associated protein 3

Target Function

RNA-binding protein that plays a role in the regulation of alternative splicing and influences mRNA splice site selection and exon inclusion. Binds preferentially to the 5'-[AU]UAAA-3' motif in vitro. Binds optimally to RNA containing 5'-[AU]UAA-3' as a bipartite motif spaced by more than 15 nucleotides. Binds poly(A). RNA-binding abilities are down-regulated by tyrosine kinase PTK6. Involved in splice site selection of vascular endothelial growth factor. In vitro regulates CD44 alternative splicing by direct binding to purine-rich exonic enhancer. Can regulate alternative splicing of neurexins NRXN1-3 in the laminin G-like domain 6 containing the evolutionary conserved neurexin alternative spliced segment 4 (AS4) involved in neurexin selective targeting to postsynaptic partners such as neuroligins and LRRTM family members. Targeted, cell-type specific splicing regulation of NRXN1 at AS4 is involved in neuronal glutamatergic synapse function and plasticity. May regulate expression of KHDRBS2/SLIM-1 in defined brain neuron populations by modifying its alternative splicing. Can bind FABP9 mRNA. May play a role as a negative regulator of cell growth. Inhibits cell proliferation.; (Microbial infection) Involved in post-transcriptional regulation of HIV-1 gene expression.

Target Subcellular Location

Nucleus. Note=Localized in a compartment adjacent to the nucleolus, but distinct from the peri-nucleolar one.
