ocular albinism type 1 protein (G protein-coupled receptor 143 or GPR143, OA1) (4th Cytoplasmic Domain) antibody

Antigen: ocular albinism type 1 protein (G protein-coupled receptor 143 or GPR143, OA1)

Binding Site: 4th Cytoplasmic Domain

Clonality: Polyclonal

Host: Rabbit

Application: Immunohistochemistry (IHC), Western Blotting (WB)

Catalog no.: ABIN350533

Additional Information

UniProt: P51810

Immunogen: A synthetic peptide from the 4th cytoplasmic domain of human ocular albinism type 1 protein (G protein-coupled receptor 143 or GPR143, OA1) conjugated to an immunogenic carrier protein was used as the immunogen.

Format: Lyophilized

Description: Ocular albinism type 1 protein is a conserved integral membrane protein with seventransmembrane domains. It is expressed in the eye and epidermal melanocytes. FUNCTION: Not known; binds heterotrimeric G proteins. SUBCELLULAR LOCATION: Melanosome membrane; Multi-pass membrane protein. Note: Targeted to intracellular organelles, namely the melanosomes in pigment cells. TISSUE SPECIFICITY: Exclusively expressed in pigment cells. DISEASE: Defects in GPR143 are the cause of ocular albinism type 1 (OA1); also known as Nettleship-Falls type ocular albinism. OA1 is an X-linked disorder characterized by severe impairment of visual acuity, retinal hypopigmentation and the presence of macromelanosomes. Also known as: G-protein coupled receptor 143, ocular albinism type 1 protein, GPR143, OA1.

Specificity: Appears to be specific for OA1.

Application Details

Application Notes: IHC, WB. A dilution of 1 : 300 to 1 : 2000 is recommended. The optimal dilution should be determined by the end user. Not yet tested in other applications.

Purity: whole serum

Purification: Immunoaffinity chromatography

Storage: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Restrictions: For Research Use only
