CC   -!- FUNCTION: Transcription factor that plays a critical role in innate
CC       immunity by activating expression of type I interferon (IFN) IFNA and
CC       INFB and inflammatory cytokines downstream of endolysosomal toll-like
CC       receptors TLR7, TLR8 and TLR9 (PubMed:11303025, PubMed:15695821,
CC       PubMed:22412986, PubMed:25326418, PubMed:32433612). Regulates the
CC       transcription of type I IFN genes (IFN-alpha and IFN-beta) and IFN-
CC       stimulated genes (ISG) by binding to an interferon-stimulated response
CC       element (ISRE) in their promoters (By similarity). Can efficiently
CC       activate both the IFN-beta (IFNB) and the IFN-alpha (IFNA) genes and
CC       mediate their induction downstream of the TLR-activated, MyD88-
CC       dependent pathway (By similarity). Key transcription factor regulating
CC       the IFN response during SARS-CoV-2 infection (PubMed:33440148).

CC   -!- ACTIVITY REGULATION: Maintained as a monomer in an autoinhibited state
CC       (PubMed:25326418, PubMed:18836453, PubMed:22412986). Phosphorylation
CC       and activation follow the following steps: innate adapter protein TASL
CC       recruits IRF5, thereby licensing IRF5 for phosphorylation by IKBKB
CC       (PubMed:32433612). Phosphorylated IRF5 dissociates from the adapter
CC       proteins, dimerizes, and then enters the nucleus to induce IFNs
CC       (PubMed:25326418, PubMed:32433612). {ECO:0000269|PubMed:18836453,

CC       etiology. It is subdivided into Crohn disease and ulcerative colitis
CC       phenotypes. Crohn disease may affect any part of the gastrointestinal
CC       tract from the mouth to the anus, but most frequently it involves the
CC       terminal ileum and colon. Bowel inflammation is transmural and
CC       discontinuous; it may contain granulomas or be associated with
CC       intestinal or perianal fistulas. In contrast, in ulcerative colitis,
CC       the inflammation is continuous and limited to rectal and colonic
CC       mucosal layers; fistulas and granulomas are not observed. Both diseases
CC       include extraintestinal inflammation of the skin, eyes, or joints.
CC       {ECO:0000269|PubMed:17881657}. Note=Disease susceptibility is
CC       associated with variants affecting the gene represented in this entry.
CC   -!- DISEASE: Systemic lupus erythematosus 10 (SLEB10) [MIM:612251]: A
CC       chronic, relapsing, inflammatory, and often febrile multisystemic
CC       disorder of connective tissue, characterized principally by involvement
CC       of the skin, joints, kidneys and serosal membranes. It is of unknown
CC       etiology, but is thought to represent a failure of the regulatory
CC       mechanisms of the autoimmune system. The disease is marked by a wide
CC       range of system dysfunctions, an elevated erythrocyte sedimentation
CC       rate, and the formation of LE cells in the blood or bone marrow.

CC       associated with variants affecting the gene represented in this entry.
CC   -!- DISEASE: Rheumatoid arthritis (RA) [MIM:180300]: An inflammatory
CC       disease with autoimmune features and a complex genetic component. It
CC       primarily affects the joints and is characterized by inflammatory
CC       changes in the synovial membranes and articular structures, widespread
CC       fibrinoid degeneration of the collagen fibers in mesenchymal tissues,
CC       and by atrophy and rarefaction of bony structures.
