{PDOC51804} {PS51804; ZF_C2HC_LYAR} {BEGIN} ************************************** * Zinc finger C2HC LYAR-type profile * ************************************** Zinc finger (ZF) proteins are a large family of metalloproteins that utilize zinc for structural purposes. Zinc coordinates to a combination of cysteine thiol and histidine imidazole residues within the ZF polypetide sequence resulting in a folded and functional protein. Ly-1 antibody reactive clone (Lyar), which is known to be expressed abundantly in the testis, encodes a nucleolar protein that contain a LYAR-type C2HC zinc finger motif and three nuclear localization signals. It is a nucleolar protein abundantly expressed in spermatocytes and spermatids, but not sperm. LYAR forms a complex with the nucleolin, which is one of the most abundant proteins in the nucleolus [1,2,3]. The profile we developed covers the entire LYAR-type C2HC zinc finger. -Sequences known to belong to this class detected by the profile: ALL. -Other sequence(s) detected in Swiss-Prot: NONE. -Last update: June 2016 / First entry.
