Where is Drp1 located in the cell?
mitochondria
Immunofluorescence and subcellular fractionation show that endogenous Drp1 is localized to mitochondria, which is also consistent with a role in mitochondrial division.
What does Drp1 stand for?
Dynamin-related Protein 1 (Drp1) Promotes Structural Intermediates of Membrane Division.
What is the role of Drp1 dnm1 in apoptosis?
Dominant-Negative Drp1 Inhibits Apoptosis- Associated Inner Mitochondrial Membrane Depolarization and Cytochrome C Release. The intracellular redistribution of Drp1 during apoptosis together with the DrpK38A-mediated block of mitochondrial fission led us to consider whether Drp1 might participate in apoptosis.
What chromosome is OPA1 gene on?
chromosome 3
Mgm1/OPA1 is localized to the mitochondrial intermembrane space, where it is tightly bound to the outer surface of the inner membrane. Changes in mitochondria caused by overexpression of wild type or mutant forms or loss of protein are described. Linked to dominant optic atrophy on chromosome 3.
What chromosome is OPA1 on?
chromosome 3q29
The OPA1 gene (MIM #605290) is located on chromosome 3q29 and encodes for a ubiquitously expressed dynamin-related GTPase, which is imported into mitochondria by an N-terminal import sequence and localizes to the inner membrane facing the intermembrane space [49, 50].
Do mitochondria have 70S ribosomes?
Ribosomes found in eukaryotic organelles such as mitochondria or chloroplasts have 70S ribosomes—the same size as prokaryotic ribosomes. However, outside of those two organelles, ribosomes in eukaryotic cells are 80S ribosomes, composed of a 40S small subunit and a 60S large subunit.
Why is mitochondrial fission important?
Fission is needed to create new mitochondria, but it also contributes to quality control by enabling the removal of damaged mitochondria and can facilitate apoptosis during high levels of cellular stress.
