The protein encoded by this gene associates with class II major histocompatibility complex (MHC) and is an important chaperone that regulates antigen presentation for immune response. It also serves as cell surface receptor for the cytokine macrophage migration inhibitory factor (MIF) which, when bound to the encoded protein, initiates survival pathways and cell proliferation. This protein also interacts with amyloid precursor protein (APP) and suppresses the production of amyloid beta (Abeta). Multiple alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Aug 2011]
A study in mice demonstrated that the CD74 was upregulated in monocytes from septic animals compared to sham controls and was selected as a key gene (rank 2.2) in a final eight-gene machine learning model for sepsis identification, which achieved high diagnostic accuracy with AUROC values of 0.904 and 0.924 in independent test datasets [Li et al. DOI:10.1007/s00011-025-02068-7]. In human skin, the CD74 was identified as an MHC class II chaperone marker expressed in endothelial cell clusters within a comprehensive spatiotemporal atlas of acute and chronic wound healing [Liu et al. DOI:10.1016/j.stem.2024.11.013].
