Tissue SpecificityExpressed in the gastrointestinal, reproductive, and urinary tracts (at protein level) (PubMed:1429669, PubMed:12021776, PubMed:9588893, PubMed:22359618). Expressed in Paneth cells of the small intestine (at protein level) (PubMed:1429669, PubMed:12021776). Expressed throughout the urothelium of the lower urinary tract and in the collecting tubules of the kidney (at protein level) (PubMed:22359618). Expressed in stratified squamous epithelial cells of the female genital tract epithelia, such as in vagina, ectocervix, endocervix, endometrium, and fallopian tube (at protein level) (PubMed:9588893). Endometrial expression correlates with stages of the menstrual cycle: Expression is low during the early proliferative phase, increased during the mid- to late proliferative phase, peaks during the early secretory phase of the cycle, and decreases during the mid- to late secretory phase (PubMed:9588893). {ECO:0000269|PubMed:12021776, ECO:0000269|PubMed:1429669, ECO:0000269|PubMed:22359618, ECO:0000269|PubMed:9588893}.

Subcellular location [CC]Secreted {ECO:0000269|PubMed:12021776, ECO:0000269|PubMed:9588893}. Cytoplasmic vesicle, secretory vesicle {ECO:0000269|PubMed:12021776, ECO:0000269|PubMed:9588893}. Note=Stored as propeptide HD5(20-94) in secretory granules of small intestinal Paneth cells and found in the ileum lumen as processed mature peptides, predominantly in the HD5(63-94) form (PubMed:12021776). Peptides HD5(20-94), HD5(23-94) and HD5(29-94) are found within tissues, HD5(20-94) being the predominant intracellular form. Peptides HD5(56-94) and HD5(63-94) are found in the extracellular milieu, HD5(63-94) being the most abundant form (PubMed:12021776). Secreted into the female genital tract lumen (PubMed:9588893). {ECO:0000269|PubMed:12021776, ECO:0000269|PubMed:9588893}.
