THE BINDING DOMAIN OF SKN-1 IN COMPLEX WITH DNA: A NEW DNA-BINDING MOTIF

Structural highlights

1skn is a 3 chain structure with sequence from Caeel. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Gene:	SKN-1 (CAEEL)
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum

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]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

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]
