mouse brain tissue were subjected to SDS PAGE followed by western blot with FNab06743(PQBP1 antibody) at dilution of 1:500
Background
Probably functions as scaffold protein that is part of numerous complexes and thereby plays a role in pre-mRNA splicing, transcription regulation and neuron development. Required for normal alternative splicing of target pre-mRNA species(PubMed:23512658). May suppress the ability of POU3F2 to transactivate the DRD1 gene in a POU3F2 dependent manner. Can activate transcription directly or via association with the transcription machinery. May be involved in ATXN1 mutant-induced cell death. The interaction with ATXN1 mutant reduces levels of phosphorylated RNA polymerase II large subunit.
