ZNF143 (Zinc Finger Protein 143, SPH-binding Factor, Selenocysteine tRNA Gene Transcription-activating Factor, hStaf, SBF, STAF)

ZNF143 is a 69kD (unglycosylated) member of the GLI C2H2-type zinc-finger protein family. Human ZNF143 is 638aa in length. A second isoform is produced from the deletion of residues 39-69. The protein contains seven C2H2-type zinc fingers, and is expressed in all tissues tested with greatest expression in the ovary. Functionally, ZNF143 serves as a transcriptional activator. Its other functions include acting as an activator for the gene for selenocysteine tRNA (tRNAsec), binding to the SPH motif of small nuclear RNA (snRNA) gene promoters, and participating in efficient U6 RNA polymerase III transcription through its interaction with CHD8. Human ZNF143 shares 97% aa sequence identity with mouse ZNF143.||Applications:|Suitable for use in Immunocytochemistry.
