Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: A synthetic peptide corresponding to a sequence in the middle region of human ICA1, identical to the related mouse and rat sequences.
- Molecular weight context: reported MW: 60-65 kDa; calculated MW: 54645 MW
- Reactivity: Human,Mouse,Rat
- Applications: WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
Islet cell autoantigen 1; Islet cell autoantigen 1. Islet cell autoantigen 1 is a protein that in humans is encoded by the ICA1 gene. It is mapped to 7p22. This gene encodes a protein with an arfaptin homology domain that is found both in the cytosol and as membrane-bound form on the Golgi complex and immature secretory granules. What’s more, this protein is believed to be an autoantigen in insulin-dependent diabetes mellitus and primary Sjogren's syndrome. Several transcript variants encoding two different isoforms have been found for this gene. Functional note: May play a role in neurotransmitter secretion. . Reported localization: Cytoplasm, cytosol . Golgi apparatus membrane ; Peripheral membrane protein . Cytoplasmic vesicle, secretory vesicle membrane ; Peripheral membrane protein . Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane ; Peripheral membrane protein . Predominantly cytosolic. Also exists as a membrane-bound form which has been found associated with synaptic vesicles and also with the Golgi complex and immature secretory granules. Expression/tissue context: Expressed abundantly in pancreas, heart and brain with low levels of expression in lung, kidney, liver and thyroid.
