Gene Information

human ... PDCD1(5133)

General description

PD-1 (programmed death-1) is an immunosuppressive molecule, which is also known as PDCD1 (programmed cell death 1). It is located on chromosome 2q37.3. It is a member of immunoglobulin receptor superfamily.


a 16 amino acid peptide from near the carboxy-terminus of human PD-1.

Biochem/physiol Actions

PD-1 (programmed death-1) gene is sensitive to systemic lupus erythematosus (SLE). Polymorphisms in PD-1 may participate in the growth of EOC (epithelial ovarian cancer). It acts as a negative regulator of T cells. It is also responsible for immune escape mediated by tumor cell.


The action of this antibody can be blocked using blocking peptide SBP4065.

Physical form

Solution in phosphate buffered saline containing 0.02% sodium azide
