cd33 signal peptide N-terminal CD33 signal peptide expressing SEAP in HEK293 - Signal peptidedatabase MPLLLLLPLLWAGALA The Crucial Role of the CD33 Signal Peptide in Protein Secretion and Function

Signal peptidedatabase The CD33 signal peptide is a critical N-terminal sequence that dictates the proper targeting and secretion of the CD33 protein, a key player in the immune system. As a myeloid cell surface antigen, CD33 belongs to the immunoglobulin superfamily and is a sialic-acid-binding immunoglobulin-like lectin (Siglec). Its presence is primarily observed on cells of the myelomonocytic lineage, including leukaemic cells, but it is notably absent from haematopoietic stem cells. Understanding the function and characteristics of the CD33 signal peptide is essential for various research applications, particularly in the field of protein expression and therapeutic development.

Signal peptides, also known as leader sequences, are short amino acid sequences typically found at the N-terminus of nascent proteins. Their primary role is to facilitate the translocation of the protein across the endoplasmic reticulum membrane, thereby initiating the secretory pathway. The CD33 signal peptide has garnered significant attention due to its efficacy and widespread use as a standard for protein secretion, particularly in mammalian cell expression systems like HEK293 and CHO hosts.2016年5月19日—Western blot quantification of secreted SEAP levels using CD33 signal peptides. ...
