PAR3-beta Putative adapter protein involved in asymmetrical cell division and cell polarization processes. May play a role in the formation of epithelial tight junctions. Belongs to the PAR3 family. Highly expressed in kidney, lung and skeletal muscle. Expressed at intermediate levels in brain, heart, placenta, liver and pancreas. Isoform 1 is predominant, while isoform 2 and isoform 3 are expressed at lower levels. 6 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
