Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in acrosome assembly; cilium assembly; and positive regulation of transcription by RNA polymerase II. Acts upstream of or within cellular response to leukemia inhibitory factor. Predicted to be located in cytoplasm and nucleus. Is expressed in several structures, including central nervous system; liver; ovary; primitive streak; and sensory organ. Orthologous to human RFX2 (regulatory factor X2). [provided by Alliance of Genome Resources, Jul 2025]

Interplay of RFX transcription factors 1, 2 and 3 in motile ciliogenesis.
Title: Interplay of RFX transcription factors 1, 2 and 3 in motile ciliogenesis.
RFX2 plays a major and specific function in spermiogenesis.
Title: RFX2 Is a Major Transcriptional Regulator of Spermiogenesis.
Data show that that Rfx2 is expressed in motile cilia in mouse and zebrafish embryos
Title: RFX2 is essential in the ciliated organ of asymmetry and an RFX2 transgene identifies a population of ciliated cells sufficient for fluid flow.
RFX2 is potentially an important transcriptional regulator in pachytene spermatocytes; Rfx2 itself is a good candidate to be regulated by A-MYB, which is essential for meiotic progression.
Title: RFX2 is a candidate downstream amplifier of A-MYB regulation in mouse spermatogenesis.
RFX2 may play roles in haploid cells during mouse spermatogenesis
Title: Differential expression of Rfx1-4 during mouse spermatogenesis.
Rfx2 is most abundantly expressed in tissues rich in highly ciliated cells, such as olfactory sensory neurons, and is predicted to be important to cilia.
Title: Tissue expression patterns identify mouse cilia genes.
RFX2 is strongly expressed in pachytene spermatocytes, remains high in early round spermatids, and declines only in advance of nuclear condensation. Maximum expression correlates well with the appearance of H1t.
Title: RFX2 is a potential transcriptional regulatory factor for histone H1t and other genes expressed during the meiotic phase of spermatogenesis.

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.
