It binds to the poly(A) tail of eukaryotic mRNA molecules facilitating the translation process and aiding in mRNA stability. The protein is expressed ubiquitously throughout the cell with a mass of approximately 70 kDa. Some variations like PABPC1 exist in different contexts but the core functions remain consistent across these variations.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThis protein plays an essential role in translation initiation. PABP interacts with eukaryotic initiation factor 4G (eIF4G) which fosters the formation of the eIF4F complex an assembly critical for ribosome recruitment to mRNA. By linking the 5’ cap structure to the poly(A) tail PABP enhances translational efficiency and RNA integrity. Through these interactions it helps maintain normal cellular function and adapts to changes in the cellular environment.\u003cbr\u003e\nPathways\u003cbr\u003e\nPoly(A) binding protein is central to the RNA metabolic process. It supports the canonical mRNA decay pathway by interacting with deadenylase complexes which initiate mRNA decay. Another key pathway involves the regulation of nonsense-mediated decay where PABP helps distinguish between normal and aberrant mRNAs. Proteins such as XRN1 and eIF4E closely interact with PABP to execute these pathways efficiently.\u003cbr\u003e\nIssues with the poly(A) binding protein affect both cancer and neurodegenerative conditions. Aberrant expression or malfunction of PABP leads to defects in mRNA regulation potentially resulting in tumorigenesis due to disrupted cell cycle control. PABP also interacts with proteins like TDP-43 implicated in neurodegenerative diseases affecting RNA processing and potentially contributing to conditions like Amyotrophic Lateral Sclerosis (ALS). The consistent involvement of PABP in these processes highlights its importance to human health.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46844246524073,"sku":"ab21060","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab21060","provider":"Iright","version":"1.0","type":"link"}
