function:Likely to be a transcription factor specific for squamous epithelium and for the constituent keratinocytes at a stage either prior to or at the very beginning of terminal differentiation. May play a role in the differentiation of spermatozoa and oocytes.,PTM:Phosphorylation on Ser-537 and Ser-541 leads to cytoplasmic localization.,similarity:Contains 6 C2H2-type zinc fingers.,subcellular location:Relocates to the midpiece of the flagellum during late spermiogenesis in spermatids.,tissue specificity:Expressed in epidermis, testis and foreskin, and to a lower extent in thymus, spleen, mammary glands, placenta, brain and heart.,
Nucleus . Cytoplasm . Nucleus, nucleoplasm . Relocates to the midpiece of the flagellum during late spermiogenesis in spermatids. .
In epidermis, primarily detected in cells of the basal or immediately suprabasal layers (at protein level) (PubMed:16891417). In hair follicles, mainly expressed in the outer root sheath (at protein level) (PubMed:8034748). Expressed in epidermis, testis and foreskin, and to a lower extent in thymus, spleen, mammary glands, placenta, brain and heart (PubMed:9687312). Expressed in the ovary, notably in oocytes (PubMed:30010909).
