CC -!- FUNCTION: Transcriptional regulator which regulates the development,
CC differentiation, and function of thymic epithelial cells (TECs) both in
CC the prenatal and postnatal thymus. Acts as a master regulator of the
CC TECs lineage development and is required from the onset of
CC differentiation in progenitor TECs in the developing fetus to the final
CC differentiation steps through which TECs mature to acquire their full
CC functionality. Regulates, either directly or indirectly the expression
CC of a variety of genes that mediate diverse aspects of thymus
CC development and function, including MHC Class II, DLL4, CCL25, CTSL,
CC CD40 and PAX1. Regulates the differentiation of the immature TECs into
CC functional cortical TECs (cTECs) and medullary TECs (mTECs)
CC (PubMed:22072979). Essential for maintenance of mTECs population in the
CC postnatal thymus (PubMed:19955175). Involved in the morphogenesis and
CC maintenance of the three-dimensional thymic microstructure which is
CC necessary for a fully functional thymus (PubMed:21109991). Plays an
CC important role in the maintenance of hematopoiesis and particularly T
CC lineage progenitors within the bone marrow niche with age
CC (PubMed:24184560). Essential for the vascularization of the thymus
CC anlage (PubMed:19853842). Promotes the terminal differentiation of
CC epithelial cells in the epidermis and hair follicles, partly by
CC negatively regulating the activity of protein kinase C
CC (PubMed:17459087). {ECO:0000269|PubMed:17459087,

CC ECO:0000269|PubMed:24184560}.
CC -!- SUBCELLULAR LOCATION: Nucleus.
CC -!- TISSUE SPECIFICITY: Bone marrow (at protein level). Expressed in thymus
CC and skin. {ECO:0000269|PubMed:24184560}.
CC -!- DISEASE: Note=Defects in FOXN1 are the cause of the nude/severe
CC combined immunodeficiency (SCID) phenotype which is characterized by
CC athymia and hairlessness. Mice develop largely normal hair follicles
CC and produce hair shafts. However, presumably because of a lack of
CC certain hair keratins, the hair shafts that are generated twist and
CC coil in the hair follicle infundibulum, which becomes dilated. Since
CC hair shafts fail to penetrate the epidermis, macroscopic nudity results
CC and generates the grossly misleading impression that nude mice are
CC hairless. {ECO:0000269|PubMed:2288204, ECO:0000269|PubMed:7969402}.
CC -!- DISRUPTION PHENOTYPE: Mice exhibit nude skin phenotype and acute thymic
CC atrophy with a severe early block in thymic epithelial cells (TECs)
CC differentiation. A more severe deterioration seen in medullary thymic
CC epithelial cells (mTECs) than in cortical thymic epithelial cells
CC (cTECs). {ECO:0000269|PubMed:19955175, ECO:0000269|PubMed:21109991,
