Function
Collagen XVII, previously called BP180, is a transmembrane protein which plays a critical role in maintaining the linkage between the intracellular and the extracellular structural elements involved in epidermal adhesion. COL17A1 is the official name of the gene. It encodes the alpha chain of type XVII collagen. Collagen XVII is a transmembrane protein, like collagen XIII, XXIII and XXV. Collagen XVII is a structural component of hemidesmosomes, multiprotein complexes at the dermal-epidermal basement membrane zone that mediate adhesion of keratinocytes to the underlying membrane. It also appears to be a key protein in maintaining the integrity of the corneal epithelium.[5] Mutations in this gene are associated with both generalized atrophic benign and junctional epidermolysis bullosa,[6] as well as recurrent corneal erosions, and expression of this gene is abnormal in various cancers. Two homotrimeric forms of type XVII collagen exist. The full length form is the transmembrane protein. A soluble form, referred to as either ectodomain or LAD-1, is generated by proteolytic processing of the full length form.

Tissue Specificity
Detected in skin. In the cornea, it is detected in the epithelial basement membrane, the epithelial cells, and at a lower level in stromal cells (at protein level). Stratified squamous epithelia. Found in hemidesmosomes. Expressed in cornea, oral mucosa, esophagus, intestine, kidney collecting ducts, ureter, bladder, urethra and thymus but is absent in lung, blood vessels, skeletal muscle and nerves.
Post-translational Modification
The intracellular/endo domain is disulfide-linked.; Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.; The ectodomain is shedded from the surface of keratinocytes resulting in a 120-kDa soluble form, also named as 120 kDa linear IgA disease antigen. The shedding is mediated by membrane-bound metalloproteases. This cleavage is inhibited by phosphorylation at Ser-544.

Western blot analysis of Collagen XVII on different lysates with Rabbit anti-Collagen XVII antibody (ET1602-14) at 1/5,000 dilution.
Lane 1: A431 cell lysate (15 µg/Lane)
Lane 2: Mouse skin tissue lysate (20 µg/Lane)
Lane 3: Rat skin tissue lysate (20 µg/Lane)
Predicted band size: 148 kDa
Observed band size: 130、180 kDa
Exposure time: 40 seconds; ECL: K1802;4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (ET1602-14) at 1/5,000 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature. -

Western blot analysis of Collagen XVII on different lysates with Rabbit anti-Collagen XVII antibody (ET1602-14) at 1/1,000 dilution.
Lane 1: Wild-type caski whole cell lysate (10 µg).
Lane 2/3: Collagen XVII knockdown caski whole cell lysate (10 µg).
Predicted band size: 148 kDa
Observed band size: 130、180 kDa
Exposure time: 1 minutes 40 seconds; ECL: K1801;4-20% SDS-PAGE gel.
ET1602-14 was shown to specifically react with Collagen XVII in wild-type caski cells. Weakened bands were observed when Collagen XVII knockdown samples were tested. Wild-type and Collagen XVII knockdown samples were subjected to SDS-PAGE. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM in TBST for 1 hour at room temperature. The primary antibody (ET1602-14) at 1/1,000 dilution were used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature. -
Immunohistochemical analysis of paraffin-embedded human skin tissue with Rabbit anti-Collagen XVII antibody (ET1602-14) at 1/200 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (ET1602-14) at 1/200 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX. -
