Protein kinase C coordinates histone H3 phosphorylation and acetylation

open access: yeseLife, 2015
The re-assembly of chromatin following DNA replication is a critical event in the maintenance of genome integrity. Histone H3 acetylation at K56 and phosphorylation at T45 are two important chromatin modifications that accompany chromatin assembly.

The C Terminus of Ku80 activates the DNA-dependent protein kinase catalytic subunit [PDF]

open access: yes, 1999
Ku is a heterodimeric protein with double-stranded DNA end-binding activity that operates in the process of nonhomologous end joining. Ku is thought to target the DNA-dependent protein kinase (DNA-PK) complex to the DNA and, when DNA bound, can interact ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Diacylglycerol kinase control of protein kinase C

open access: yesBiochemical Journal, 2019
Abstract The diacylglycerol kinases (DGK) are lipid kinases that transform diacylglycerol (DAG) into phosphatidic acid (PA) in a reaction that terminates DAG-based signals. DGK provide negative regulation to conventional and novel protein kinase C (PKC) enzymes, limiting local DAG availability in a tissue- and subcellular-restricted ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Phosphorylation of Hepatitis C Virus Core Protein by Protein Kinase A and Protein Kinase C

open access: yesVirology, 2002
Hepatitis C virus (HCV) core protein can form capsid-like particles and is believed to be the viral capsid protein. Besides its structural functions, this protein is also known to possess multiple regulatory functions. In this article, we have studied the possible phosphorylation of HCV core protein in two different human liver-derived cell lines Huh7 ...

CCT4 promotes tunneling nanotube formation

open access: yesFEBS Letters, EarlyView.
Tunneling nanotubes (TNTs) are membranous tunnel‐like structures that transport molecules and organelles between cells. They vary in thickness, and thick nanotubes often contain microtubules in addition to actin fibers. We found that cells expressing monomeric CCT4 generate many thick TNTs with tubulin.

Involvement of tyrosine-specific protein kinase and protein kinase C in J774A.1 macrophage functions activated by Tinospora cordifolia

open access: yesJournal of Ayurveda and Integrative Medicine, 2017
Background: Macrophages are the first line of defense and constitute important participant in the bi-directional interaction between innate and specific immunity. Macrophages are in a quiescent form and get activated when given a stimulus.

Protein Kinase C Life Cycle: Explained Through Systems Biology Approach

open access: yesFrontiers in Physiology, 2022
Protein kinase C (PKC) enzymes are a family of kinases that mediate signal transduction originating at the cell surface. Most cell membranes can contain functional PKC enzymes.

Regulation of sertoli-germ cell adherens junction dynamics via changes in protein-protein interactions of the N-cadherin-β-catenin protein complex which are possibly mediated by c-Src and myotubularin-related protein 2: An in vivo study using an androgen suppression model [PDF]

open access: yes, 2005
Using a well characterized model of cell-cell actin-based adherens junction (AJ) disruption by suppressing the intratesticular testosterone level in adult rats with testosterone-estradiol implants, we have confirmed earlier findings that Sertoli-germ ...
