Supplementary information

PAX5 also called B-cell-specific activator protein (BSAP) plays an important role in regulating gene expression during B-cell development. PAX5 is a transcription factor with an approximate mass of 50-55 kDa. It expresses mainly in B cells and in certain regions of the brain and testis. This protein binds DNA and controls the transcription of genes necessary for B-cell commitment and identity. Through processes like alternative splicing PAX5 generates multiple isoforms that contribute to various functional roles in its expressed locations.
Biological function summary

PAX5 regulates the differentiation and maintenance of B-lymphocytes. It controls various genes critical for B-cell lineage commitment while repressing those involved in other lineages like T-cells and myeloid cells. PAX5 is part of a larger transcriptional complex interacting with other transcription factors to perform its function. During B-cell maturation PAX5 activates a specific gene set that helps shape the B-cell receptor repertoire a process important for effective immune responses.

Pathways

PAX5 integrates into key pathways such as the B-cell receptor signaling and JAK-STAT pathways. These pathways regulate processes like cell proliferation differentiation and apoptosis. In the B-cell receptor signaling PAX5 works alongside proteins like CD19 and BTK facilitating the transmission of activation signals necessary for B-cell survival. Connections in the JAK-STAT pathway involve interactions that promote gene expression changes necessary for B-cell functional activity further modulating the immune system's readiness.

PAX5 is significantly associated with B-cell acute lymphoblastic leukemia (B-ALL) and non-Hodgkin lymphoma. In B-ALL mutations or deletions in PAX5 often lead to impaired B-cell development and uncontrolled cell proliferation. PAX5 mutations influence proteins like EBF1 and IL7R which are pivotal in B-cell progenitor activity and leukemogenesis. abnormalities in PAX5 expression or function can disrupt normal immune function leading to B-cell associated cancers and impairing immune surveillance highlighting its importance in maintaining immune system health.

Target data

Transcription factor that plays an essential role in commitment of lymphoid progenitors to the B-lymphocyte lineage (PubMed : 10811620, PubMed : 27181361). Fulfills a dual role by repressing B-lineage inappropriate genes and simultaneously activating B-lineage-specific genes (PubMed : 10811620, PubMed : 27181361). In turn, regulates cell adhesion and migration, induces V(H)-to-D(H)J(H) recombination, facilitates pre-B-cell receptor signaling and promotes development to the mature B-cell stage (PubMed : 32612238). Repression of the cohesin-release factor WAPL causes global changes of the chromosomal architecture in pro-B cells to facilitate the generation of a diverse antibody repertoire (PubMed : 32612238).. (Microbial infection) Plays an essential role in the maintenance of Epstein-Barr virus genome copy number within the host cell by promoting EBNA1/oriP-dependent binding and transcription (PubMed : 31941781). Participates also in the inhibition of lytic EBV reactivation by modulating viral BZLF1 activity (PubMed : 23678172).
