TRANSCRIPTIONAL REPRESSOR GCF


HGNC Approved Gene Symbol: GCFC2

Cytogenetic location: 2p12     Genomic coordinates (GRCh38): 2:75,662,705-75,713,122 (from NCBI)


TEXT

Cloning and Expression

Kageyama and Pastan (1989) cloned a cDNA for a human transcriptional regulator, which they called GCF, that represses transcription of certain genes and is encoded by a 3-kb mRNA.

Johnson et al. (1992) found that the GCF gene is widely expressed in human tissues and cell lines.

Takimoto et al. (1999) also cloned a GCF cDNA and found 3 major revisions in the sequence originally published by Kageyama and Pastan (1989). By 5-prime RACE, Takimoto et al. (1999) determined that the 5-prime end is 308 nucleotides shorter than the original sequence, that a 'T' at position 787 is not observed, and that there is an insertion of 114 nucleotides between positions 851 and 852 of the previous sequence. The revisions resulted in a cDNA consisting of 2,661 nucleotides encoding a 781-amino acid protein. SDS-PAGE analysis determined that GCF is expressed as an approximately 120-kD protein. Gel shift analysis also revealed that the revised GCF has no sequence-specific DNA-binding activity. Takimoto et al. (1999) concluded that to avoid errors in the sequencing it is important to confirm cDNA sequences by isolating and sequencing more than 1 clone and by comparing the cDNA with the genomic DNA sequence.


Mapping

By in situ hybridization, Johnson et al. (1992) mapped the GCF gene to chromosome 2p11.2-p11.1.
