Function

[SKN1_CAEEL] Required to specify the fate of ventral blastomeres in the early embryo, and postembryonically for the development of the intestine. Directly regulates expression of zygotically expressed med-1 and med-2 to direct mesendoderm development.^[1] ^[2]

Publication Abstract from PubMed

The DNA-binding domain of Skn-1, a developmental transcription factor that specifies mesoderm in C. elegans, is shown by X-ray crystallography to have a novel fold in which a compact, monomeric, four-helix unit organizes two DNA-contact elements. At the C-terminus, a helix extends from the domain to occupy the major groove of DNA in a manner similar to bZip proteins. Skn-1, however, lacks the leucine zipper found in all bZips. Additional contacts with the DNA are made by a short basic segment at the N-terminus of the domain, reminiscent of the 'homeodomain arm'.

A new DNA-binding motif in the Skn-1 binding domain-DNA complex.,Rupert PB, Daughdrill GW, Bowerman B, Matthews BW Nat Struct Biol. 1998 Jun;5(6):484-91. PMID:9628487^[3]
