Anti-hPat1b antibodies enable researchers to detect and measure the hPat1b antigen in biological samples. This target is a reported synonym of the PATL1 gene, which encodes PAT1 homolog 1, processing body mRNA decay factor. This protein is a reported RNA-binding protein involved in deadenylation-dependent decapping of mRNAs, leading to the degradation of mRNAs. The human version of hPat1b has a canonical amino acid length of 770 residues and a protein mass of 86.9 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. hPat1b is a member of the PAT1 protein family.
