Supplementary information

PRDM1 also referred to as Blimp-1 is a transcription factor involved in the regulation of gene expression. It has a molecular mass of approximately 106 kDa. This protein is expressed in a variety of cell types including B lymphocytes T cells and in certain tissues such as the intestine. It plays an important role in controlling the transcriptional programs necessary for cellular differentiation and development. PRDM1 functions mainly by binding to specific DNA sequences to repress the transcription of target genes acting as a master regulator in the immune system.

Biological function summary

PRDM1/Blimp-1 influences important processes like plasma cell differentiation particularly in the immune response. It is not part of a larger protein complex but functions by recruiting chromatin-modifying enzymes to silence target gene expression. In B cells it promotes the transition to plasma cell formation by repressing genes that would otherwise inhibit this differentiation. Blimp1 also plays a role in maintaining the differentiation state by regulating genes involved in cell survival and function.

Pathways

PRDM1/Blimp1 is primarily associated with pathways such as the B cell maturation and immunoglobulin secretion pathways. It acts downstream of signaling cascades initiated by factors like CD40 and IL-21. PRDM1 works closely with other transcription factors like XBP-1 in the pathway to drive effective plasma cell differentiation. By repressing factors such as Pax5 and Bcl6 PRDM1 ensures the proper execution of the differentiation program within these pathways.

Malfunctions in PRDM1/Blimp1 are linked to autoimmune conditions like systemic lupus erythematosus and some types of lymphomas. Altered function or expression can disrupt immune homeostasis leading to the production of autoantibodies. Disorders may arise when PRDM1 fails to repress genes like those regulated by Bcl6 contributing to unregulated cell growth and abnormal immune activity. Additionally its dysfunction can be observed in certain gastrointestinal disorders where it is pivotal for maintaining gut immune homeostasis.

Target data

Transcription factor that mediates a transcriptional program in various innate and adaptive immune tissue-resident lymphocyte T cell types such as tissue-resident memory T (Trm), natural killer (trNK) and natural killer T (NKT) cells and negatively regulates gene expression of proteins that promote the egress of tissue-resident T-cell populations from non-lymphoid organs. Plays a role in the development, retention and long-term establishment of adaptive and innate tissue-resident lymphocyte T cell types in non-lymphoid organs, such as the skin and gut, but also in other nonbarrier tissues like liver and kidney, and therefore may provide immediate immunological protection against reactivating infections or viral reinfection (By similarity). Binds specifically to the PRDI element in the promoter of the beta-interferon gene (PubMed : 1851123). Drives the maturation of B-lymphocytes into Ig secreting cells (PubMed : 12626569). Associates with the transcriptional repressor ZNF683 to chromatin at gene promoter regions (By similarity). Binds to the promoter and acts as a transcriptional repressor of IRF8, thereby promotes transcription of osteoclast differentiation factors such as NFATC1 and EEIG1 (By similarity).
