pfam15801: zf-C6H2 (This model is not part of the current CDD release)
zf-MYND-like zinc finger, mRNA-binding
zf-C6H2 is an unusual zinc-finger similar to zf-MYND, pfam01753.This zinc-finger is found at the N-terminus of Pfam families Exo_endo_phos pfam03372 and Peptidase_M24 pfam00557. The domain is missing in prokaryotic methionine aminopeptidases, and is a unique type of zinc-finger domain. It consists of a C2-C2 zinc-finger motif similar to the RING finger family followed by a C2H2 motif similar to zinc-fingers involved in RNA-binding. In yeast the domain chelates zinc in a 2:1 ratio. The domain is found in yeast, plants and mammals. The domain is necessary for the association of the methionine aminopeptidase with the ribosome and the normal processing of the peptidase.
