IGF2BP1: a novel binding protein of p38 MAPK

Molecular and Cellular Biochemistry
Jacob Rini, Moorthy Anbalagan

Abstract

Signal transduction pathways control various biological processes in cells leading to distinct cellular functions. Protein-protein interactions and post-translational modifications are the physiological events that occur in signaling pathway. p38 MAPK are known to be involved in regulating wide range of cellular processes by interacting and activating relevant signaling molecules by means of phosphorylation. Deregulation of p38 MAPK is associated with various pathological conditions. In order to get an insight into the role played by p38 MAPK in cellular signaling, studies were carried out to identify proteins that interact with p38 MAPK. Mass spectrometry was used to identify the proteins present in p38 MAPK complex obtained by co-immunoprecipitation. Based on mass spectrometry data, here we report insulin-like growth factor-II binding protein 1 (IGF2BP1) as a novel interacting partner of p38 MAPK. IGF2BP1 is a RNA-binding protein predominantly known to be involved in tumor progression. To reconfirm the mass spectrometry data, in silico analysis was carried out. Based on different models predicted in silico, we report the possible interaction domains of p38MAPK and IGF2BP1. Considering the involvement of p38MAPK and IGF2BP1 in...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
