Olfactory receptor.

Bleomycin hydrolase; The normal physiological role of BLM hydrolase is unknown, but it catalyzes the inactivation of the antitumor drug BLM (a glycopeptide) by hydrolyzing the carboxamide bond of its B- aminoalaninamide moiety thus protecting normal and malignant cells from BLM toxicity; Belongs to the peptidase C1 family.

Caspase-14 subunit p20, intermediate form; Non-apoptotic caspase which is involved in epidermal differentiation. Seems to play a role in keratinocyte differentiation and is required for cornification. Regulates maturation of the epidermis by proteolytically processing filaggrin. In vitro is equally active on the synthetic caspase substrates WEHD-ACF and IETD-AFC. Involved in processing of prosaposin in the epidermis. May be involved in retinal pigment epithelium cell barrier function (By similarity). Belongs to the peptidase C14A family.

Stefin-3; This is an intracellular thiol proteinase inhibitor; Belongs to the cystatin family.

Desmocollin-1; Component of intercellular desmosome junctions. Involved in the interaction of plaque proteins and intermediate filaments mediating cell-cell adhesion. May contribute to epidermal cell positioning (stratification) by mediating differential adhesiveness between cells that express different isoforms. Linked to the keratinization of epithelial tissues.

Corneodesmosin; Important for the epidermal barrier integrity.

Calmodulin-4; Implicated in the early stage of ectopic ossification.

Keratinocyte differentiation-associated protein; May act as a soluble regulator of keratinocyte differentiation. May play an important role in embryonic skin morphogenesis (By similarity).

Magnesium transporter NIPA4; Acts as a Mg(2+) transporter. Can also transport other divalent cations such as Ba(2+), Mn(2+), Sr(2+) and Co(2+) but to a much less extent than Mg(2+). May be a receptor for ligands (trioxilins A3 and B3) from the hepoxilin pathway (By similarity); Belongs to the NIPA family.
