CD74 Antibody (YA5590)

CD74 Antibody (YA5590) is a mouse-derived and non-conjugated IgG2a monoclonal antibody, targeting to CD74. It can be applicated for IHC-P, WB, ICC/IF, ELISA assays, in the background of human.

The CD74 protein is integral to the MHC class II antigen processing pathway, exerting a critical role by stabilizing peptide-free class II alpha/beta heterodimers shortly after their synthesis. Furthermore, CD74 guides the transport of this complex from the endoplasmic reticulum to compartments where peptide loading onto class II molecules occurs. Beyond its involvement in antigen presentation, CD74 enhances T-cell responses through interaction with CD44. Additionally, CD74 acts as a chaperone for mature cathepsin L (CTSL), stabilizing its conformation by binding to the active site. This chaperone function aids in maintaining a pool of mature enzyme within endocytic compartments and the extracellular space of antigen-presenting cells (APCs), illustrating the multifaceted role of CD74 in modulating immune responses at various stages of antigen processing and presentation.
