Cell 50:919-930(2013). CC -!- FUNCTION: Inhibitor of cathepsin G, kallikrein-8 and thrombin. May CC play an important role in the inner ear in the protection against CC leakage of lysosomal content during stress. May be involved in the CC regulation of serine proteinases present in the brain or CC extravasated from the blood. {ECO:0000269|PubMed:17761692}. CC -!- SUBUNIT: Forms a complex with the monomeric form of beta-tryptase. CC {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:17761692, CC ECO:0000269|PubMed:20451170}. CC -!- TISSUE SPECIFICITY: Expressed in the inner ear hair cells, CC keratinocytes of hair follicles and epidermis in abdominal skin. CC {ECO:0000269|PubMed:17761692, ECO:0000269|PubMed:20451170}. CC -!- DEVELOPMENTAL STAGE: At 13.5 dpc, weakly detected in utricle CC sensory epithelium but not in hair cells. At 16.5 dpc, more CC prominently detected in crista hair cells. Hair cell expression is CC sustained in postnatal mice. In cochlea, detected in cochlear hair CC cells in embryo and in hair cells and the greater epithelial ridge CC (GER) region in early postnatal age. CC {ECO:0000269|PubMed:20451170}. CC -!- SIMILARITY: Belongs to the serpin family. Ov-serpin subfamily. CC {ECO:0000305}.
