Background

Mitochondria play a central role in cellular energy metabolism and are essential organelles in eukaryotes. In humans, 13 proteins are encoded by the mitochondrial genome while the vast majority of mitochondrial proteins are encoded by the nuclear genome. As a result, most mitochondrial proteins are synthesized as precursors in the cytoplasm and imported across mitochondrial membranes by one or more translocase protein complexes (1). The translocase of the outer mitochondrial membrane (TOM complex) facilitates the import of proteins through the outer mitochondrial membrane, while the complementary translocase of the inner membrane (TIM complex) is responsible for protein transport to the mitochondrial matrix. The TOM complex consists of the receptors TOM20, TOM22, TOM70, and the channel-forming protein TOM40 (1). TOM20 is localized in the outer mitochondrial membrane and initially recognizes precursors with a presequence to facilitate protein import across the outer mitochondrial membrane (2). In a sequential process, recognition of the presequence by TOM20 is followed by tethering of the presequence to the TOM40 protein complex for efficient protein import (3).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

TOM22 (E3F4M) Rabbit mAb

Western Blotting Image 1: TOM22 (E3F4M) Rabbit mAb Expand Image
Western blot analysis of extracts from various cell lines using TOM22 (E3F4M) Rabbit mAb.
Western Blotting Image 2: TOM22 (E3F4M) Rabbit mAb Expand Image
Western blot analysis of extracts from 293T cells, either transfected with non-targeting siRNA (293T siNT) or siRNA targeting TOM22 (293T siTOM22), using TOM22 (E3F4M) Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower). The TOM22 (E3F4M) Rabbit mAb confirms silencing of TOM22 expression, while the β-Actin (D6A8) Rabbit mAb #8457 is used as a loading control.
Immunoprecipitation Image 1: TOM22 (E3F4M) Rabbit mAb Expand Image
Immunoprecipitation of TOM22 protein from KYSE-70 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is TOM22 (E3F4M) Rabbit mAb. Western blot analysis was performed using TOM22 (E3F4M) Rabbit mAb. Mouse Anti-rabbit IgG (Conformation Specific) (L27A9) mAb (HRP Conjugate) #5127 was used as the secondary antibody.
