May function in the assembly or regulation of proteins in the cornified envelope. The LIM domain may be involved in homotypic or heterotypic associations and may function to localize sciellin to the cornified envelope (By similarity). May become cross-linked to membrane proteins by transglutaminase. Expressed in the upper layers of stratified epithelia, including, ependyma and choroid plexus of the brain ventricles. Strong expression was seen in 17-17.5 day-old embryos. Expression was also detected in the amnion of 17.5 day-old embryo.
