Anti-Rab acceptor 1 (prenylated) antibodies are used in antigen-specific immunodetection in biological samples. The target Rab acceptor 1 (prenylated) is a known alias name of the protein Rab acceptor 1, encoded by the RABAC1 gene in humans. This 185-amino acid residue protein is a member of the PRA1 protein family. It is localized to the cell membrane, cytoplasmic vesicles, Golgi, and cytoplasm of the cell. In terms of tissue expression, it is ubiquitously expressed across many tissue types. Other synonyms for Rab acceptor 1 (prenylated) include PRA1, PRA1, and PRAF1.
