Summaries for WFIKKN2 Gene

Entrez Gene Summary for WFIKKN2 Gene

  • The WFIKKN1 protein contains a WAP domain, follistatin domain, immunoglobulin domain, two tandem Kunitz domains, and an NTR domain. This gene encodes a WFIKKN1-related protein which has the same domain organization as the WFIKKN1 protein. The WAP-type, follistatin type, Kunitz-type, and NTR-type protease inhibitory domains may control the action of multiple types of proteases. [provided by RefSeq, Jul 2008]

GeneCards Summary for WFIKKN2 Gene

WFIKKN2 (WAP, Follistatin/Kazal, Immunoglobulin, Kunitz And Netrin Domain Containing 2) is a Protein Coding gene. GO annotations related to this gene include serine-type endopeptidase inhibitor activity and metalloendopeptidase inhibitor activity. An important paralog of this gene is TFPI.

UniProtKB/Swiss-Prot for WFIKKN2 Gene

  • Protease-inhibitor that contains multiple distinct protease inhibitor domains. Probably has serine protease- and metalloprotease-inhibitor activity. Inhibits the biological activity of mature myostatin, but not activin (By similarity).
