Rabbit anti-Human PPP1R8 Polyclonal Antibody

Uniprot Id

Q12972

Target Species

Human

Target Name

PPP1R8

Target Full Name

Nuclear inhibitor of protein phosphatase 1

Target Function

Inhibitor subunit of the major nuclear protein phosphatase-1 (PP-1). It has RNA-binding activity but does not cleave RNA and may target PP-1 to RNA-associated substrates. May also be involved in pre-mRNA splicing. Binds DNA and might act as a transcriptional repressor. Seems to be required for cell proliferation.; Isoform Gamma is a site-specific single-strand endoribonuclease that cleaves single strand RNA 3' to purines and pyrimidines in A+U-rich regions. It generates 5'-phosphate termini at the site of cleavage. This isoform does not inhibit PP-1. May be implicated in mRNA splicing.

Target Subcellular Location

Nucleus. Nucleus speckle. Note=Primarily, but not exclusively, nuclear.; [Isoform Gamma]: Cytoplasm. Note=Found mainly in the cytoplasm.

Target Tissue Specificity

Ubiquitously expressed, with highest levels in heart and skeletal muscle, followed by brain, placenta, lung, liver and pancreas. Less abundant in kidney. The concentration and ratio between isoforms is cell-type dependent. Isoform Alpha (>90%) and isoform
