The grainyhead subfamily, whose members include GRHL1, GRHL2 and GRHL3, consist of orthologs of the Drosophila grainyhead (grh) gene. In Drosophila, grh is involved in early dorsal/ventral patterning and tissue development. The grainyhead subfamily members are, therefore, believed to act as transcription factors during development. GRHL1, GRHL2 and GRHL3 are localized to the nucleus and exist as homodimers or as heterodimers with each other. GRHL3, also known as sister of mammalian grainyhead (SOM) or transcription factor CP2-like 4 (TFCP2L4), is a 626 amino acid protein. Transgenic GRHL3-null mouse embryos have displayed many neural tube defects, indicating a significant role of GRHL3 in neural tube formation during development. GRHL3 is widely expressed and exists as 4 isoforms produced by alternative splicing. Isoform 2 has been shown to be prostate specific.
