General description

SAMM50 is a component of the sorting and assembly machinery (SAM) complex of the outer mitochondrial membrane. The SAM complex has a role in integrating beta-barrel proteins into the outer mitochondrial membrane (Humphries et al., 2005 [PubMed 15644312]).[supplied by OMIM

Immunogen

SAMM50 (AAH07830, 1 a.a. ~ 468 a.a) full-length recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Biochem/physiol Actions

Sorting and assembly machinery (SAM) 50 helps in aggregation of β-barrel proteins into the outer mitochondrial membrane (OMM). SAM 50, along with mitofilin and coiled-coil-helix-coiled-coil-helix domain containing 3 (CHCHD3), plays a vital role in maintaining mitochondrial shape, the morphology of cristae, and the assembly of respiratory complexes. Elevated expression of SAMM50 leads to mitochondrial fragmentation in HeLa cells under the influence of dynamin-related protein (Drp) 1. Depleted expression of SAM 50 affects assembly and steady-state level of voltage-dependent anion-selective channel (VDAC), which is essential for transport of metabolite across OMM.

Mitochondrial fission and fusion activities are important for cell survival and function. Drp1 is a GTPase protein responsible for mitochondrial division, and SAMM50 is responsible for protein sorting and assembly. We demonstrated that SAMM50 overexpression results in Drp1-dependent mitochondrial fragmentation
