Pnn Gene Summary [Rat]
Predicted to enable DNA binding activity. Predicted to be involved in RNA splicing and mRNA processing. Predicted to act upstream of or within cell-cell adhesion. Predicted to be located in cytoplasm; desmosome; and nuclear speck. Predicted to be part of catalytic step 2 spliceosome and exon-exon junction complex. Orthologous to human PNN (pinin, desmosome associated protein). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Pnn often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
