TissueNA
Tissue SpecificityAbundantly expressed in the differentiating cortex of growing (anagen) hair. Expression is restricted to the keratinocytes of the hair cortex and is absent from inner root sheath and medulla. Expressed in malignant lymph node tissue in breast carcinoma tissue. {ECO:0000269|PubMed:7490069, ECO:0000269|PubMed:7528047, ECO:0000269|PubMed:9457912}.
