The ARMCX2 antibody is a research tool designed to detect the ARMCX2 protein, encoded by the *ARMCX2* gene (Armadillo Repeat-Containing X-Linked 2). This gene belongs to the ARMCX family located on the X chromosome, implicated in mitochondrial dynamics and intracellular transport. ARMCX2 is thought to regulate mitochondrial trafficking, particularly in neurons, by interacting with proteins like MIRO-1. which coordinates mitochondrial movement along microtubules. Dysregulation of ARMCX2 has been associated with neurodevelopmental disorders, cancer progression, and metabolic diseases, as it may influence cell migration, proliferation, and apoptosis.
ARMCX2 antibodies are widely used in techniques such as Western blotting, immunohistochemistry, and immunofluorescence to study protein expression, localization, and function in cellular and tissue contexts. Researchers employ these antibodies to explore ARMCX2's role in diseases like glioblastoma or neuroblastoma, where its expression is often altered. Commercially available antibodies are typically validated for specificity using knockout controls or siRNA-mediated silencing.
Despite its potential significance, ARMCX2's exact molecular mechanisms remain under investigation. The antibody thus serves as a critical reagent for elucidating its biological contributions to mitochondrial homeostasis, neuronal function, and disease pathways, offering insights for therapeutic targeting.
