    Protocol

    Specificity / Sensitivity

    PTBP1 (E5O2S) Rabbit mAb recognizes endogenous levels of total PTBP1 protein. This antibody does not cross-react with PTBP2 protein.

    Species Reactivity:

    Human, Mouse, Rat, Monkey

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val10 of human PTBP1 protein.

    Background

    PTBP1 and PTBP2 are highly related pre-mRNA binding proteins that silence the splicing of alternative exons (1,2). While PTBP1 is widely expressed, PTBP2, also known as neural PTB or nPTB, is expressed in post-mitotic neurons. In other cell types, PTBP2 transcripts are alternatively spliced by PTBP1, which leads to nonsense-mediated decay (3). PTBP1 and 2 bind to similar regions across the transcriptome, but PTBP1 has a stronger repressive property likely due to cofactors such as Raver1 and Matrin3 (4-6). Overexpression of PTBPs in various cancers has been observed, leading to alternative splicing of key proteins in oncogenic pathways (6-9).
