The UniProt recommended name is Glycine amidinotransferase, mitochondrial (GATM), also known as L-arginine:glycine amidinotransferase or AGAT. GATM transfers an amidino group from arginine to glycine, producing guanidinoacetate, which is subsequently methylated to creatine by GAMT. Creatine and phosphocreatine serve as rapid energy buffers in tissues with fluctuating ATP demand, including muscle and brain.\u003cbr\u003e\u003cbr\u003eFunctionally, GATM antibody identifies a 423-amino-acid mitochondrial matrix enzyme that catalyzes a reversible transamidination reaction dependent on pyridoxal phosphate (PLP) as a cofactor. This reaction provides the foundation for creatine synthesis, linking amino acid metabolism with cellular energy storage. The enzyme's activity supports energy homeostasis by ensuring adequate creatine production for high-energy phosphate transfer through the phosphocreatine system.\u003cbr\u003e\u003cbr\u003eThe GATM gene is located on chromosome 15q21.1 and encodes a homotetrameric enzyme targeted to mitochondria via an N-terminal transit peptide. GATM is primarily expressed in kidney, pancreas, and liver, where it supplies guanidinoacetate for systemic creatine synthesis. In muscle and neural tissues, creatine generated downstream of GATM activity is phosphorylated by creatine kinase to form phosphocreatine, maintaining ATP levels during high metabolic activity. Deficiency or mutation of GATM causes creatine deficiency syndrome, characterized by neurological impairment and muscle weakness.\u003cbr\u003e\u003cbr\u003eGATM antibody is widely used in studies of amino acid metabolism, energy homeostasis, and mitochondrial function. It is a valuable marker for assessing creatine biosynthesis and mitochondrial enzyme integrity. Reduced GATM activity is linked to metabolic and neurological disorders, while upregulation has been observed under energy stress and oxidative conditions. The enzyme's function connects arginine metabolism, urea cycle intermediates, and ATP regeneration.\u003cbr\u003e\u003cbr\u003eStructurally, GATM consists of an active-site lysine residue forming a Schiff base with PLP, enabling catalysis of amidino transfer. The enzyme forms stable homotetramers that ensure efficient substrate channeling and regulation. GATM activity is modulated by substrate availability and feedback inhibition from creatine levels. It interacts with mitochondrial transport proteins to coordinate substrate exchange across the inner membrane. A GATM antibody supports research applications including western blotting, immunohistochemistry, and metabolic flux analysis, providing insights into energy metabolism and mitochondrial health.\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence:\u003c\/strong\u003e visualize subcellular distribution and cell-to-cell heterogeneity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry:\u003c\/strong\u003e map target signal in tissue context and compare regions\/phenotypes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and signal shifts at single-cell resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e support antibody-based quantification in assay formats where applicable.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=GATM - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=GATM - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=GATM - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/GATM - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=GATM+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047307960685,"sku":"FY12963","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_dc085a86-7e4e-46d4-80f9-ea27ebd24e7e.jpg?v=1782237068","url":"https:\/\/www.ebiohippo.com\/products\/gatm-antibody-glycine-amidinotransferase-mitochondrial-bha17135865","provider":"BioHippo","version":"1.0","type":"link"}
