Predicted to enable peptidase inhibitor activity. Predicted to act upstream of or within negative regulation of cell growth involved in cardiac muscle cell development. Predicted to be located in extracellular region. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Jul 2025]
A study in human corpus cavernosum tissue demonstrated that PI16 is a key marker for classifying fibroblast subclusters, specifically defining PI16+ FB clusters (FB3, FB4) [Zhao et al. DOI:10.1038/s41467-022-31950-9]. Further research integrating single-cell and spatial transcriptomics in human and rat corpus cavernosum confirmed PI16 as a fibroblast subtype marker, showing that PI16+ FBs exhibited a high enrichment score in the septum pectiniforme and the upper pole region near the dorsal side of the human CC [Yin et al.
