Rabbit anti-Human PTPN12 Polyclonal Antibody

Uniprot Id

Q05209

Target Species

Human

Target Name

PTPN12

Target Full Name

Tyrosine-protein phosphatase non-receptor type 12

Target Function

Dephosphorylates a range of proteins, and thereby regulates cellular signaling cascades. Dephosphorylates cellular tyrosine kinases, such as ERBB2 and PTK2B/PYK2, and thereby regulates signaling via ERBB2 and PTK2B/PYK2. Selectively dephosphorylates ERBB2 phosphorylated at 'Tyr-1112', 'Tyr-1196', and/or 'Tyr-1248'.

Target Subcellular Location

Cytoplasm. Cell junction, focal adhesion. Cell projection, podosome.

Target Protein Families

Protein-tyrosine phosphatase family, Non-receptor class 4 subfamily

Target Synonyms

PTPG1; PTP-PEST; PTPN12

Target Background

The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains a C-terminal PEST motif, which serves as a protein-protein interaction domain, and may regulate protein intracellular half-life. This PTP was found to bind and dephosphorylate the product of the oncogene c-ABL and thus may play a role in oncogenesis. This PTP was also shown to interact with, and dephosphorylate, various products related to cytoskeletal structure and cell adhesion, such as p130 (Cas), CAKbeta/PTK2B, PSTPIP1, and paxillin. This suggests it has a regulatory role in controlling cell shape and mobility. Alternative splicing results in multiple transcript variants encoding distinct isoforms.
