Ly6K (Lymphocyte antigen 6 locus K; also CO16) is a 26-27 kDa member of the Ly-6 antigen family of molecules. It has restricted expression, being described in testis and skin. Ly6K is found in/on carcinomas, and is known to circulate in normal and tumor-patient blood. Mature human Ly6K is a 121 amino acid (aa) GPI-linked (presumed) glycoprotein. It is synthesized as a 165 aa preproprecursor that contains a 17 aa signal sequence, a 121 aa mature region (aa 18-138), and a 27 aa C‑terminal propeptide. There are two potential splice variants, one that shows a 48 aa substitution, and another that shows a 33 aa substitution for aa 73-165. It is not clear if mouse Ly6K is a true molecular ortholog of human Ly6K. In any event, over aa 18-138, human Ly6K shares 39% aa identity with mouse Ly6K.

Scientific Data Images for Human Ly6K Antibody (1053415)
Detection of Ly6K in HeLa (positive) and K562 (negative) cells.
Ly6K was detected in immersion fixed HeLa (positive) and K562 (negative) cells using Mouse Anti-Human Ly6K Monoclonal Antibody (Catalog # MAB66481) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Detection of Human Ly6K by Western Blot.
Western blot shows lysates of human Testes. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Ly6K Monoclonal Antibody (Catalog # MAB66481) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Ly6K at approximately 26 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.Applications for Human Ly6K Antibody (1053415)
