研究背景

機能:

Dynamin-related GTPase that is essential for normal mitochondrial morphology by regulating the equilibrium between mitochondrial fusion and mitochondrial fission. Coexpression of isoform 1 with shorter alternative products is required for optimal activity in promoting mitochondrial fusion. Binds lipid membranes enriched in negatively charged phospholipids, such as cardiolipin, and promotes membrane tubulation. The intrinsic GTPase activity is low, and is strongly increased by interaction with lipid membranes. Plays a role in remodeling cristae and the release of cytochrome c during apoptosis (By similarity). Proteolytic processing in response to intrinsic apoptotic signals may lead to disassembly of OPA1 oligomers and release of the caspase activator cytochrome C (CYCS) into the mitochondrial intermembrane space (By similarity). Plays a role in mitochondrial genome maintenance.

Inactive form produced by cleavage at S1 position by OMA1 following stress conditions that induce loss of mitochondrial membrane potential, leading to negative regulation of mitochondrial fusion.

Isoforms that contain the alternative exon 4b (present in isoform 4 and isoform 5) are required for mitochondrial genome maintenance, possibly by anchoring the mitochondrial nucleoids to the inner mitochondrial membrane.

PTMs:

PARL-dependent proteolytic processing releases an antiapoptotic soluble form not required for mitochondrial fusion. Cleaved by OMA1 at position S1 following stress conditions.

Cleavage at position S2 is mediated by YME1L. Cleavage may occur in the sequence motif Leu-Gln-Gln-Gln-Ile-Gln (LQQQIQ). This motif is present in isoform 2, isoform 3, isoform 4 and isoform 7, but is absent in the displayed isoform 1 and in isoform 5.

Application: WB    Species: Human    Sample:

Figure 7 Mitochondrial dynamics participate in osteogenesis mediated by FGFR/FGFR2-AMPK pathway: (A) Mito-tracker red and mitochondria 2D analysis showed more fragmented or punctate mitochondria with fewer and shorter branches in the MT group, while there were widely reticular mitochondria with longer branches in the WT group. (B) qRT-PCR and Western blot analysis demonstrated that the expressions of mitochondrial-fusion-related factors Mfn2 and Opa1 were downregulated, however, the expression of mitochondrial-fission-related factor Drp1 was upregulated in the MT group compared to the WT group. (C) Mito-tracker red and mitochondria 2D analysis showed a filamentous network of mitochondria with more and longer branches widely spread in the cytoplasm in the siFGFR2 group. (D) qPCR and Western blot analysis showed that the expression of fusion-related genes Mfn2 and Opa1 was increased and the expression of fission-related gene Drp1 was decreased in the siFGFR2 group. (E) After treatment with Compound C, the morphology of the mitochondria which should have tended to split adopted a fused reticular structure with more and longer branches, as shown by Mito-tracker red and mitochondria 2D analysis. (F) Western blot analysis showed the level of MFN2 and OPA1 was increased and then level of DRP1 was decreased, as induced by Compound C. p values were significant at * p < 0.05, ** p < 0.01, *** p < 0.001 and **** p < 0.0001.
