Mitochondrial fusion - Wikipedia
网页Mitochondrial fusion enables content mixing within a mitochondrial population, thereby preventing permanent loss of essential components. Cells with reduced mitochondrial fusion show a subpopulation of mitochondria that lack mtDNA nucleoids.

Mitochondrial dynamics in health and disease: mechanisms and …
网页2023年9月6日 · Mitochondrial dynamics refers to the changing process of fission, fusion, mitophagy and transport, which is crucial for optimal function in signal transduction and metabolism.
Mitochondrial Division and Fusion in Metabolism - PMC
网页Mitochondrial fusion consists of outer membrane fusion and inner membrane fusion. Outer membrane fusion is mediated by mitofusin while inner membrane fusion is mediated by Opa1. Mitochondrial fusion is regulated by proteosomal degradation of mitofusins, proteolytic processing of Opa1 and production of GTP.
Mitochondrial fission and fusion - PMC - National Center for ...
网页Fission and fusion are active processes which require many specialized proteins, including mechanical enzymes that physically alter mitochondrial membranes, and adaptor proteins that regulate the interaction of these mechanical proteins with organelles.
Mitochondrial Fusion - an overview | ScienceDirect Topics
网页Mitochondrial fusion is a process by which two adjacent mitochondria are fused to form a more elongated mitochondria (or mitochondrial network). In mammals, this process is regulated by three large GTPases, mitofusin 1 (MFN1), mitofusin 2 (MFN2) and optic atrophy gene 1 (OPA1).
Mitofusins, from Mitochondria to Metabolism - Cell Press
网页2016年3月3日 · Through fusion and fission events, mitochondria share membranes, solutes, metabolites, and proteins, as well as electrochemical gradients, making them electrically coupled. Mitochondrial fusion is a two-step process requiring three GTPases: Mfn1 and Mfn2 for OMM fusion and OPA1 for IMM fusion.
