Rabbit anti-Human PTPRR Polyclonal Antibody

Uniprot Id

Q15256

Target Species

Human

Target Name

PTPRR

Target Full Name

Receptor-type tyrosine-protein phosphatase R

Target Function

Sequesters mitogen-activated protein kinases (MAPKs) such as MAPK1, MAPK3 and MAPK14 in the cytoplasm in an inactive form. The MAPKs bind to a dephosphorylated kinase interacting motif, phosphorylation of which by the protein kinase A complex releases the MAPKs for activation and translocation into the nucleus.

Target Subcellular Location

[Isoform Alpha]: Cell membrane; Single-pass type I membrane protein.; [Isoform Delta]: Cytoplasm, perinuclear region. Note=Locates to the perinuclear areas within the cytoplasm.; [Isoform Gamma]: Cytoplasm, perinuclear region. Note=Locates to the perinuclear areas within the cytoplasm.

Target Protein Families

Protein-tyrosine phosphatase family, Receptor class 7 subfamily

Target Tissue Specificity

Expressed in brain, placenta, small intestine, stomach, uterus and weakly in the prostate. Isoform alpha has been observed only in the brain. Isoform gamma is expressed in brain, placenta and uterus. Isoform delta is expressed in brain, kidney, placenta,

Target Background

The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP possesses an extracellular region, a single transmembrane region, and a single intracellular catalytic domain, and thus represents a receptor-type PTP. Silencing of this gene has been associated with colorectal cancer. Multiple transcript variants encoding different isoforms have been found for this gene. This gene shares a symbol (PTPRQ) with another gene, protein tyrosine phosphatase, receptor type, Q (GeneID 374462), which is also located on chromosome 12.
