  • lacks the hinge-encoding exons 5-8 and represses potently IL17 and IL21 gene transcription
  • acts as a dominant-negative regulator of RORC-mediated gene regulation and the balance between the full-length RORC and the novel repressor isoform may arbitrate IL17 production in human T cells

    basic FUNCTION
  • ligand activated transcription factor, essential for lymphoid organogenesis (lymph nodes and Peyer's patches) and playing an important regulatory role in thymopoeisis
  • functions as an important link between the circadian clock and the transcriptional regulation of several metabolic genes
  • both RORC-overexpressed CD4(+) T cells and reduced Treg cells might contribute to the development of Sjögren syndrome (SS)-like sialadenitis
  • plays a significant role in the dysregulated immune response associated with systemic lupus erythematosus (SLE)
  • is critical for the differentiation and proliferation of Th17 cells associated with several chronic autoimmune diseases
  • RORC/IL17A axis influences VEGFA production and neovascular retinopathy by mechanisms involving neuroglia
  • directs the differentiation of Th17 cells, that mediate pathological immune responses responsible for autoimmune diseases, including psoriasis and multiple sclerosis
  • master regulator of the Th17/IL17 pathway that plays crucial roles in the pathogenesis of autoimmunity
  • RORC, and RORA are expressed in Th17 cells and have been suggested to play a role in Th17 differentiation
  • overlapping role of RORC and RORA in human Th17 cell differentiation through regulation of a defined common set of Th17 genes

    a component
    small molecule
  • ID2 and RORC are sequentially up-regulated during lymphoid tissue inducer (LTi) cell development, matching two waves of differentiation with opposite requirements for NOTCH1 signaling
  • LY9/SLAMF6 signaling mediates increased nuclear abundance and recruitment of RORC to the proximal IL17A promoter, resulting in increased trans-activation and gene expression
  • transcription factor NFIL3 suppresses T(H)17 cell development by directly binding and repressing the RORC promoter
  • USP17 stabilizes RORC protein expression by reducing RORC polyubiquitination at its Lys-360 residue
  • SOX5 and MAF cooperatively induce Th17 cell differentiation via the induction of RORC as downstream targets of STAT3
  • SIRT1 increases RORC transcriptional activity, enhancing Th17 cell generation and function
  • TRAF5, known as an E3 ubiquitin protein ligase and signal transducer, interacts with and ubiquitinates RORC via Lys-63-linked polyubiquitination, and stabilizes the RORC protein level depending on its RING finger domain
  • is a key transcription factor involved in Th17 cell differentiation through direct transcriptional activation of interleukin 17(A) (IL17A)
  • EP300, which has histone acetyltransferase (HAT) activity, interacts with and acetylates RORC at its K81 residue
  • USP15 interacted with RORC, removed ubiquitin from K446, and stimulated RORC activity by enhancing coactivator SRC recruitment (positive role for USP15-mediated deubiquitination of RORC in Th17 differentiation)
