| Description |
Cys2His2 (C2H2)-type zinc fingers are widespread DNA binding motifs in eukaryotic transcription factors. Two cysteine and two histidine residues located in certain positions bind zinc to stabilize the structure. The number of zinc fingers in a single protein can vary over a wide range, and single zinc finger containing transcription factors are only present in plant kingdom. LIM domains coordinate one or more zinc atoms, and are named after the three proteins (LIN-11, Isl1 and MEC-3) in which they were first found. They consist of two zinc-binding motifs that resemble GATA-like Znf's, however the residues holding the zinc atom(s) are variable, involving Cys, His, Asp or Glu residues.
