Summary: This gene belongs to a family of Sp1 related genes that encode transcription factors that regulate transcription by binding to consensus GC- and GT-box regulatory elements in target genes. This protein contains a zinc finger DNA-binding domain and several transactivation domains, and has been reported to function as a bifunctional transcription factor that either stimulates or represses the transcription of numerous genes. Transcript variants encoding different isoforms have been described for this gene, and one has been reported to initiate translation from a non-AUG (AUA) start codon. Additional isoforms, resulting from the use of alternate downstream translation initiation sites, have also been noted. A related pseudogene has been identified on chromosome 13.

These findings suggest that the transcription of the b4GalT3 gene is regulated by differential DNA binding of Sp3 and Sp1 in neuroblastoma and lung cancer. The increased expression of b4GalT3 in neuroblastoma may be ascribed to the enhanced expression of Sp3, which is observed for various cancers.

expression of the nearby cyclindependent kinase inhibitor 1C (CDKN1C) gene was revealed to be upregulated after SP3 knockdown in cells that possessed non-risk alleles.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

See identical proteins and their annotated locations for NP_001017371.3

Status: REVIEWED

Description

Transcript Variant: This variant (2) is missing exons 1 and 2 found in transcript variant 1, and has a different 5' end. It initiates translation from a non-AUG (AUA) start site, and encodes an isoform (2) with a shorter N-terminus compared to isoform 1. Alternative translation initiation from downstream, in-frame AUG start codons produces shorter isoforms.
