Summary: This gene encodes an intracellular protein that is involved in the regulation of actin-filament dynamics. This protein is a major component of intranuclear and cytoplasmic actin rods. It can bind G- and F-actin in a 1:1 ratio of cofilin to actin, and it reversibly controls actin polymerization and depolymerization in a pH-dependent manner. Mutations in this gene cause nemaline myopathy type 7, a form of congenital myopathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2009]

LncRNA SOX2 overlapping transcript (SOX2-OT) expression was conspicuously elevated in prostate cancer (PC) tissues and cells. Silenced SOX2-OT could repress PC cell proliferation and migration. SOX2-OT bound with miR-369-3p and negatively correlated with miR-369-3p in PC. Cofilin 2 (CFL2) was found to be a downstream target gene of miR-369-3p.

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.

NR_028130.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) uses an alternate splice site in an internal exon, compared to variant 2. This variant is represented as non-coding because the use of the supported translational start codon, as used in variant 2, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).

NR_028131.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (4) uses an alternate splice site in an internal exon, compared to variant 2. This variant is represented as non-coding because only a short ORF would result from translation initiation at the supported start codon, as used in variant 2, and it is unclear if a downstream start codon could be used, which would also result in a short ORF.
