Product Overview
This rabbit polyclonal antibody targets pinin (gene PNN) in human, mouse and rat samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 81.6 kDa, and the supplier reports an observed band at about 82 kDa.
Pinin (PNN) is a nuclear protein that also localizes to desmosomes. In the nucleus it associates with the exon junction complex and helps regulate alternative pre-mRNA splicing, and it can influence transcription of the E-cadherin gene. Through these roles it is studied in epithelial cell adhesion and in cancer biology.

Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places pinin in the nucleus speckle and cell junction. Tissue expression noted by UniProt (human): Expressed in placenta, lung, liver, kidney, pancreas, spleen, thymus, prostate, testis, ovary, small intestine, colon, heart, epidermis, esophagus, brain and smooth and skeletal muscle. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
