Islet Cell Autoantigen 1 (ICA1), also known as ICA 69 kDa (ICA69), is a cytosolic protein that is associated with the Golgi complex and with immature secretory granules. Its N-terminal region shares similarity with arfaptins (ADP-ribosylation factor-interacting-proteins), suggesting that ICA1 likely plays a role in membrane trafficking. Human ICA-1 is a 483 amino acids (aa) protein. As a result of aa insertions, deletions and substitutions, multiple isoforms exist. Human ICA-1 shows 89% and 94% aa identity to mouse and canine ICA-1, respectively.

Scientific Data Images for Human ICA1 Antibody
Detection of ICA1 in A172 Human Cell Line by Flow Cytometry.
A172 human glioblastoma cell line was stained with Goat Anti-Human ICA1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4084, filled histo-gram) or isotype control antibody (AB-108-C, open histo-gram), followed by Phycoerythrin-conjugated Anti-Goat IgG Secondary Antibody (F0107). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.
ICA1 in paraffin-embedded human pancreas.
ICA1 was detected in immersion fixed paraffin-embedded sections of human pancreas using Goat Anti-Human ICA1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4084) at 0.5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (red; Catalog # VC004) and counterstained with hematoxylin (blue). Specific staining was localized to islets of Langerhans.
