This gene is orthologous to the mouse and rat genes and encodes a similar DNA-binding transcription factor that is thought to regulate keratin gene expression. A mutation in this gene has been correlated with T-cell immunodeficiency, the skin disorder congenital alopecia, and nail dystrophy. Alternative splicing in the 5' UTR of this gene has been observed. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: Transcriptional regulator which regulates the development, differentiation, and function of thymic epithelial cells (TECs) both in the prenatal and postnatal thymus. Acts as a master regulator of the TECs lineage development and is required from the onset of differentiation in progenitor TECs in the developing fetus to the final differentiation steps through which TECs mature to acquire their full functionality. Regulates, either directly or indirectly the expression of a variety of genes that mediate diverse aspects of thymus development and function, including MHC Class II, DLL4, CCL25, CTSL, CD40 and PAX1. Regulates the differentiation of the immature TECs into functional cortical TECs (cTECs) and medullary TECs (mTECs). Essential for maintenance of mTECs population in the postnatal thymus. Involved in the morphogenesis and maintenance of the three-dimensional thymic microstructure which is necessary for a fully functional thymus. Plays an important role in the maintenance of hematopoiesis and particularly T lineage progenitors within the bone marrow niche with age. Essential for the vascularization of the thymus anlage. Promotes the terminal differentiation of epithelial cells in the epidermis and hair follicles, partly by negatively regulating the activity of protein kinase C (By similarity). Plays a crucial role in the early prenatal stages of T-cell ontogeny (PubMed:21507891). {ECO:0000250|UniProtKB:Q61575, ECO:0000269|PubMed:21507891}. |Fork head| |lymphoid lineage cell migration into thymus| |thymus epithelium morphogenesis| |regulation of positive thymic T cell selection| |lymphoid lineage cell migration| |nail development| |positive regulation of hair follicle development| |positive regulation of hair cycle| |regulation of hair follicle development| |T cell lineage commitment| |regulation of T cell differentiation in thymus| |regulation of hair cycle| |T cell homeostasis| |positive regulation of epidermis development| |thymus development| |lymphocyte homeostasis| |positive regulation of epithelial cell differentiation| |leukocyte homeostasis| |hair follicle development| |skin epidermis development| |molting cycle process| |hair cycle process| |regulation of epidermis development| |epithelial cell proliferation| |molting cycle| |hair cycle| |T cell differentiation| |regulation of T cell differentiation| |regulation of epithelial cell differentiation| |regulation of lymphocyte differentiation| |limb development| |appendage development| |homeostasis of number of cells| |T cell activation| |lymphocyte differentiation| |cell fate commitment| |regulation of leukocyte differentiation| |keratinocyte differentiation| |epidermal cell differentiation| |regulation of T cell activation| |leukocyte differentiation| |skin development| |lymphocyte activation| |blood vessel morphogenesis| |gland development| |epidermis development| |sequence-specific DNA binding| |morphogenesis of an epithelium| |DNA-binding transcription activator activity, RNA polymerase II-specific| |regulation of hemopoiesis| |transcription by RNA polymerase II| |blood vessel development| |vasculature development| |regulation of lymphocyte activation| |cardiovascular system development| |cell population proliferation| |hemopoiesis| |tissue morphogenesis| |regulation of leukocyte activation| |hematopoietic or lymphoid organ development| |transcription, DNA-templated| |regulation of cell activation| |nucleic acid-templated transcription| |immune system development| |RNA biosynthetic process| |tube morphogenesis| |epithelial cell differentiation| |tube development| |circulatory system development| |leukocyte activation| |animal organ morphogenesis| |cell migration| |positive regulation of cell differentiation| |cell activation| |cell motility| |localization of cell| |nucleobase-containing compound biosynthetic process| |epithelium development| |heterocycle biosynthetic process| |aromatic compound biosynthetic process| |positive regulation of transcription by RNA polymerase II| |organic cyclic compound biosynthetic process| |locomotion| |defense response| |positive regulation of developmental process| |positive regulation of transcription, DNA-templated| |movement of cell or subcellular component| |DNA-binding transcription factor activity, RNA polymerase II-specific| |cellular nitrogen compound biosynthetic process| |positive regulation of nucleic acid-templated transcription| |positive regulation of RNA biosynthetic process| |homeostatic process| |regulation of immune system process| |RNA metabolic process| |cellular macromolecule biosynthetic process| |positive regulation of RNA metabolic process| |positive regulation of multicellular organismal process| |tissue development| |macromolecule biosynthetic process| |regulation of cell differentiation| |positive regulation of nucleobase-containing compound metabolic process| |positive regulation of macromolecule biosynthetic process| |positive regulation of cellular biosynthetic process| |positive regulation of gene expression| |gene expression| |positive regulation of biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp359|FK-506 30μM R07 exp359]]|-2.09| No correlation found to any other genes in chemogenomics.
