Recombinant Human DNA-binding protein RFX2 (RFX2)

Uniprot Id

P48378

Target Species

Human

Target Name

RFX2

Target Full Name

DNA-binding protein RFX2

Target Function

Transcription factor that acts as a key regulator of spermatogenesis. Acts by regulating expression of genes required for the haploid phase during spermiogenesis, such as genes required for cilium assembly and function. Recognizes and binds the X-box, a regulatory motif with DNA sequence 5'-GTNRCC(0-3N)RGYAAC-3' present on promoters. Probably activates transcription of the testis-specific histone gene H1-6.

Target Subcellular Location

Nucleus. Cytoplasm.

Target Protein Families

RFX family

Target Synonyms

DNA-binding protein RFX2; HLA class II regulatory factor RFX2; regulatory factor X 2 (influences HLA class II expression); Regulatory factor X 2; regulatory factor X2; RFX2; RFX2_HUMAN; trans acting regulatory factor 2

Target Background

This gene is a member of the regulatory factor X gene family, which encodes transcription factors that contain a highly-conserved winged helix DNA binding domain. The protein encoded by this gene is structurally related to regulatory factors X1, X3, X4, and X5. It is a transcriptional activator that can bind DNA as a monomer or as a heterodimer with other RFX family members. This protein can bind to cis elements in the promoter of the IL-5 receptor alpha gene. Two transcript variants encoding different isoforms have been described for this gene, and both variants utilize alternative polyadenylation sites.
