Cytoplasm, cytoskeleton . Nucleus . Cytoplasm . Localizes to the manchette in elongating spermatids (By similarity). Predominantly perinuclear in bronchial epithelial cells but also detected in the nucleus in some primary epithelial cells and in a number of cell lines. .
Expressed in epithelial cells of nasal polyps and in intact epithelium of bronchial biopsies from subjects with and without asthma. Strong expression in columnar cells with little or no expression in basal epithelial cells along the basement membrane. Strongly expressed in ciliated epithelial cells with lower levels in goblet cells (at protein level).
