abstract：:C2cd4c, encoded by a gene belonging to the C2cd4 family, contains a C2 domain conserved across species and is localized to the cytoplasm. To examine the role of C2cd4c in the pancreas, we studied its localization and generated C2cd4c knockout (KO) mice. C2cd4c was expressed in pancreatic endocrine progenitors at early...
