Gene name

 PCSK1N (HGNC Symbol)

Description

 Proprotein convertase subtilisin/kexin type 1 inhibitor (HGNC Symbol)

Entrez gene summary

 The protein encoded by this gene functions as an inhibitor of prohormone convertase 1, which regulates the proteolytic cleavage of neuroendocrine peptide precursors. The proprotein is further processed into multiple short peptides. A polymorphism within this gene may be associated with obesity. [provided by RefSeq, Aug 2013]
