Plays a critical role in intestinal function (PubMed:31217582). Acts by promoting the development of enteroendocrine cells (EECs) of the gastrointestinal tract and pancreas (By similarity). It is thereby required for normal enteroendocrine peptide hormone secretion (By similarity). {ECO:0000250|UniProtKB:A0A286YDK6, ECO:0000269|PubMed:31217582}. This is the function of ENSG00000284395 (PERCC1, proline and glutamate rich with coiled coil 1).
