Function

Prok2 might affect the cellular composition and development of olfactory cilia in the OE and the formation of GL in the OB, according to the interval between E18.5 and 16 weeks (PMID: 40766783). PROK2 and its receptor PROKR2 contribute to primary cilium–dependent neuronal migration pathways. Mutations cause Kallmann syndrome, a recognized ciliopathy with variable penetrance and oligogenic inheritance (PMID: 20389090).
