Goat anti Human PTBP1 antibody; recognizes an epitope within the N-terminal (NT) region of human PTBP1, otherwise known as polypyrimidine tract-binding protein 1. PTPB1 is a multi-functional, ubiquitously expressed heterogeneous nuclear ribonucleoprotein (hnRNP), implicated in pre-mRNA processing, mRNA metabolism and transport. PTPB1 contains 4 RRM motifs.

PTBP1 is highly over-expressed in glioma and, along with its brain-specific homologue PTBP2, acts as a regulator of neural precursor cell differentiation (Wang et al. 2013). There are 3 described isoforms of PTPB1 derived by alternative splicing, isoforms differ in having insertions between the RRM domains 2 and 3. Goat anti Human PTBP1 antibody is expected to recognize all isoforms of PTPB1.
