CC   -!- FUNCTION: Transcription factor that plays an essential role in
CC       commitment of lymphoid progenitors to the B-lymphocyte lineage
CC       (PubMed:9042861). Fulfills a dual role by repressing B-lineage
CC       inappropriate genes and simultaneously activating B-lineage-specific
CC       genes (PubMed:16546096). In turn, regulates cell adhesion and
CC       migration, induces V(H)-to-D(H)J(H) recombination, facilitates pre-B-
CC       cell receptor signaling and promotes development to the mature B-cell
CC       stage (PubMed:9042861, PubMed:16546096). Repression of the cohesin-
CC       release factor WAPL causes global changes of the chromosomal
CC       architecture in pro-B cells to facilitate the generation of a diverse
CC       antibody repertoire (By similarity). {ECO:0000250|UniProtKB:Q02548,
CC       ECO:0000269|PubMed:16546096, ECO:0000269|PubMed:9042861}.
CC   -!- SUBUNIT: Interacts with ETS1; this interaction alters PAX5 DNA-binding
CC       properties. Binds DNA as a monomer. Interacts with TBP; this
CC       interaction allows PAX5 to interact with the basal transcription
CC       machinery. Interacts with RB1. Interacts with TLE4 (By similarity).
CC       Interacts with DAXX (PubMed:11799127). {ECO:0000250|UniProtKB:Q02548,
CC       ECO:0000269|PubMed:11799127}.

CC       Q02650; Q9UER7: DAXX; Xeno; NbExp=4; IntAct=EBI-296260, EBI-77321;
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q02548}.
CC   -!- TISSUE SPECIFICITY: Expressed in all B-lymphoid organs, in the
CC       embryonic midbrain and in adult testis. {ECO:0000269|PubMed:1516825}.
CC   -!- PTM: O-glycosylated. {ECO:0000305}.
CC   -!- PTM: Phosphorylated by SYK. This phosphorylation plays an important
CC       role in the abolition of BLIMP1 repression by PAX5 in order to trigger
CC       plasma cell differentiation. {ECO:0000250|UniProtKB:Q02548}.
CC   -!- DISRUPTION PHENOTYPE: Mutant mice fail to produce small pre-B, B, and
CC       plasma cells and therefore lack any immunoglobulin in their serum owing
CC       to a complete arrest of B-cell development at an early stage.
