| 背景 | Cytochrome c oxidase subunit 4 isoform 1 (COX-4I1) is a 21‑22 kDa member of the cytochrome c oxidase IV family of proteins. It is a component of COX, an inner mitochondrial membrane multimeric dimer that catalyzes the transfer of electrons from cytochrome c to dioxygen. COX-4I1 is the largest of 10 distinct nuclear DNA‑encoded subunits that form each COX monomer. Human COX4-I1 is 169 amino acids (aa) in length and possesses a mitochondrial transit peptide between aa 1‑22, an ATP binding site (aa 42; 95‑100), and multiple subunit interface sequences. The ATP binding site is suggested to make COX-4I1 a regulatory subunit within the COX complex. There are two potential splice variants for COX-4I1 that show a three aa substitution for aa 81‑169, and a single Gly substitution for aa 125‑169. COX‑4I2, the product of a different gene, shares only 50% aa identity with COX-4I1. Over amino acid 23‑169, human COX4‑1 shares 78% aa identity with mouse COX‑4I1. |

Detection of Human/Mouse COX4-I1 by Western Blot. Western blot shows lysates of human brain tissue, Jurkat human acute T cell leukemia cell line, HepG2 human hepatocellular carcinoma cell line, and BaF3 mouse pro‑B cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse COX4-I1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5814) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for COX4-I1 at approximately 18 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2. | |
COX4-I1 in Human Kidney. COX4-I1 was detected in immersion fixed paraffin-embedded sections of normal human kidney using Goat Anti-Human/Mouse COX4-I1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5814) at 10 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

COX4‑I1 in HeLa Human Cell Line. COX4‑I1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Goat Anti-Human/Mouse COX4‑I1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5814) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (yellow; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to mitochondria. View our protocol for Fluorescent ICC Staining of Cells on Coverslips. | |
Detection of Human COX4‑I1 by Simple WesternTM. Simple Western lane view shows lysates of Jurkat human acute T cell leukemia cell line and HepG2 human hepatocellular carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for COX4‑I1 at approximately 24 kDa (as indicated) using 10 µg/mL of Goat Anti-Human/Mouse COX4‑I1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5814) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. |
