Zebrafish Pccb Antibody / Propionyl-CoA carboxylase beta chain

In zebrafish, Pccb is an ortholog of the human PCCB gene. Both zebrafish and human Pccb proteins share significant sequence conservation and functional similarity, especially in their roles in energy metabolism and biochemical processing. This conservation makes zebrafish an excellent model for studying the physiological and biochemical functions of Pccb, as well as its involvement in metabolic diseases. The Pccb protein functions in the mitochondria, where it catalyzes the conversion of propionyl-CoA into methylmalonyl-CoA. This reaction is important for the metabolism of certain amino acids, particularly valine, isoleucine, and threonine, as well as for the catabolism of odd-chain fatty acids. Additionally, the proper function of Pccb is critical for the synthesis of succinyl-CoA, a key intermediate in the citric acid cycle, which is essential for energy production in cells. In zebrafish, Pccb is expressed in various tissues, with prominent expression in the liver, heart, and muscle, which are important for metabolic processing and energy regulation. The enzyme is especially critical during embryonic development, where metabolic pathways must be tightly regulated to support rapid growth and tissue differentiation. Defects in Pccb function in both zebrafish and humans can lead to methylmalonic acidemia, a disorder characterized by an accumulation of methylmalonic acid and propionyl-CoA in the blood, which can cause developmental delays, neurological impairment, and metabolic complications. Studying zebrafish Pccb offers valuable insights into the molecular basis of metabolic diseases and the role of propionate metabolism in maintaining cellular homeostasis.
