Anti-F-box and leucine-rich repeat protein 13 antibodies enable researchers to detect and measure the F-box and leucine-rich repeat protein 13 antigen in biological samples. This target is a reported synonym of the FBXL13 gene, which encodes F-box and leucine rich repeat protein 13. This protein is a known component of the nexin-dynein regulatory complex (N-DRC), a key regulator of ciliary/flagellar motility which maintains the alignment and integrity of the distal axoneme and regulates microtubule sliding in motile axonemes. The human version of F-box and leucine-rich repeat protein 13 has a canonical amino acid length of 735 residues and a protein mass of 83.9 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cytoplasm of cells. F-box and leucine-rich repeat protein 13 is a member of the DRC6 protein family.
