Summary: Enables actin filament binding activity. Predicted to be involved in several processes, including homophilic cell adhesion via plasma membrane adhesion molecules; neuron development; and regulation of cytoskeleton organization. Predicted to act upstream of or within response to bacterium. Located in Z disc and focal adhesion. Human ortholog(s) of this gene implicated in dilated cardiomyopathy 1CC and hypertrophic cardiomyopathy 20. Orthologous to human NEXN (nexilin F-actin binding protein).

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.
