Poly(A)-binding proteins (PABPs) regulate mRNA fate. This review highlights PABP family functions in whole animal studies, emphasizing their biological importance and need for further research.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Background:
- Poly(A)-binding proteins (PABPs) are conserved RNA-binding proteins crucial for eukaryotic mRNA regulation.
- PABP1, a key cytoplasmic member, influences translation and mRNA stability.
- Limited understanding exists regarding other PABP family members and their roles in whole organisms.
Purpose of the Study:
- To review current and emerging knowledge on PABP family member functions in whole animal studies.
- To underscore the biological significance of PABPs based on available organismal data.
- To identify research gaps and advocate for further investigation into PABP roles.
Main Methods:
- Literature review of studies investigating PABP function in various animal models.
- Synthesis of findings from genetic disruption and functional studies of PABP family members.
- Analysis of conserved roles and species-specific functions of PABPs.
Main Results:
- PABP family members play critical, albeit not fully elucidated, roles in organismal biology.
- Disrupting PABP function has significant, yet incompletely understood, consequences in vertebrates and mammals.
- Existing animal studies demonstrate the broad biological importance of PABPs.
Conclusions:
- PABP family members are essential regulators of mRNA metabolism with profound impacts on whole organisms.
- Further intensive research, particularly in mammalian systems, is required to fully understand PABP functions.
- The review highlights the critical need for continued investigation into the biological importance of PABPs.

Allosteric Proteins-ATCase
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis...

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
