Anti-PTBP1 antibody produced in rabbit

产品说明

一般描述

Polypyrimidine tract-binding protein 1 (PTBP1) is a member of the ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs) subfamily. It has an N-terminal nuclear shuttling domain and four repeats of quasi-RNA recognition motif (RRM) domains that bind RNAs. PTBP1 is mostly expressed in all cell types. The PTBP1 gene is mapped on human chromosome 19p13.3.

免疫原

Synthetic peptide directed towards the N terminal region of human PTBP1

生化/生理作用

Polypyrimidine tract-binding protein 1 (PTBP1) plays a key role in T cell activation, spermatogenesis, and splicing. It is involved in the differentiation and development of neuronal cells, growth of embryos and erythrocytes. PTBP1 also participates in apoptosis, glycolysis, migration, metastasis, proliferation, and carcinogenesis due to its role in cancer as a splicing factor. This protein plays a major role in neurodegenerative diseases, cardiovascular diseases, colon cancer, colorectal cancer, breast cancer, glioma, and glioblastoma.
The hnRNPs are RNA-binding proteins and they complex with heterogeneous nuclear RNA (hnRNA). These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. PTBP1 protein binds to the intronic polypyrimidine tracts that requires pre-mRNA splicing and acts via the protein degradation ubiquitin-proteasome pathway. It may also promote the binding of U2 snRNP to pre-mRNAs. Alternatively spliced transcript variants encoding different isoforms have been described.
