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]
A study in human thoracopagus conjoined twins demonstrated that the WFIKKN2 gene, involved in early growth, was expressed at low levels with a hypermethylated promoter in one twin, as part of integrated multiomics analyses revealing significant local differences in DNA methylation and gene expression related to growth and development [Chen et al.
