Western blot shows lysates of Jurkat human acute T cell leukemia cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human CD1c Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5910) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for CD1c at approximately 48 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 7.

CD1c (Cluster of differentiation antigen 1c) is a 316 amino acid glycoprotein with a predicted molecular weight of 43 kDa. CD1c is a member of the CD1 family of molecules. It is expressed by thymocytes, dendritic cells and B cells, and exists as part of a noncovalent complex with 12 kDa beta 2‑microglobulin. It is found in the plasma membrane and early endosomes (but not lysosomes), and is presumed to present glycolipids and acylated peptides to T cells. Mature human CD1c is a 316 amino acid (aa) type I transmembrane glycoprotein. It contains a 285 aa extracellular domain (ECD) (aa 18‑302) plus a 10 aa cytoplasmic tail. The ECD shows one Ig‑like domain (aa 203‑296) that associates with beta 2‑microglobulin, and a TyrGlnAspIle internalization motif in the cytoplasmic tail. There are three potential splice variants. One shows a Trp substitution for aa 327‑333, a second shows an eight aa substitution for aa 298‑333, and a third shows a 50 aa substitution for aa 297‑333. There appears to be no direct mouse counterpart to human CD1c.
