lysosomal membrane ascorbate-dependent ferrireductase CYB561A3 isoform 2 [Homo sapiens]

Protein Classification

cytochrome b family protein; cytochrome b/b6( domain architecture ID 10171794)

cytochrome b family protein such as formate dehydrogenase subunit gamma or cytochrome b, a component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.| cytochrome b/b6 (PetB) is a subunit of cytochrome bc1, an 11-subunit mitochondrial respiratory enzyme; cytochrome b spans the mitochondrial membrane with 8 transmembrane helices (A-H) in eukaryotes; in plants and cyanobacteria, cytochrome b6 is analogous to cytochrome b and contains two chains: helices A-D (encoded by petB) and helices E-H (encoded by petD)

 19-188 2.77e-97

Vertebrate cytochrome b(561), CYBASC3 gene product; Cytochrome b ascorbate-dependent 3, as found in vertebrates, which might act as a ferric-chelate reductase, catalyzing the reduction of Fe(3+) to Fe(2+), such as associated with the transport of iron from the endosome to the cytoplasm. It is assumed that this protein uses ascorbate as the electron donor. Belongs to the cytochrome b(561) family, which are secretory vesicle-specific electron transport proteins. Cytochromes b(561) are integral membrane proteins that bind two heme groups non-covalently, and may have six alpha-helical trans-membrane segments.

 46-175 5.74e-33

Cytochrome b-561 / ferric reductase transmembrane domain; Cytochrome b-561 recycles ascorbate for the generation of norepinephrine by dopamine-beta-hydroxylase in the chromaffin vesicles of the adrenal gland. It is a transmembrane heme protein with the two heme groups being bound to conserved histidine residues. A cytochrome b-561 homologue, termed Dcytb, is an iron-regulated ferric reductase in the duodenal mucosa. Other homologues of these are also likely to be ferric reductases. SDR2 is proposed to be important in regulating the metabolism of iron in the onset of neurodegenerative disorders.

Vertebrate cytochrome b(561), CYBRD1 gene product; Duodenal cytochrome b or ferric-chelate reductase 3, a cytochrome b(561), as found in vertebrates, which might act as a ferric-chelate reductase, catalyzing the reduction of Fe(3+) to Fe(2+), such as associated with the transport of iron from the endosome to the cytoplasm. It is assumed that this protein uses ascorbate as the electron donor. This protein is expressed at the brush border of duodenal enterocytes and may play a role in the uptake of dietary Fe(3+), facilitating its transport into the mucosal cells. It may also be involved in the recycling of extracellular ascorbate in erythrocyte membranes, and act as a ferrireductase in epithelial cells of the respiratory system. Belongs to the cytochrome b(561) family, which are secretory vesicle-specific electron transport proteins. Cytochromes b(561) are integral membrane proteins that bind two heme groups non-covalently, and may have six alpha-helical trans-membrane segments.

Vertebrate cytochrome b(561), CYB561 gene product; Cytochrome b(561), as found in vertebrates, which might act as a ferric-chelate reductase, catalyzing the reduction of Fe(3+) to Fe(2+), such as associated with the transport of iron from the endosome to the cytoplasm. It is assumed that this protein uses ascorbate as the electron donor. Belongs to the cytochrome b(561) family, which are secretory vesicle-specific electron transport proteins. Cytochromes b(561) are integral membrane proteins that bind two heme groups non-covalently, and may have six alpha-helical trans-membrane segments.

 46-175 5.74e-33

Cytochrome b-561 / ferric reductase transmembrane domain; Cytochrome b-561 recycles ascorbate for the generation of norepinephrine by dopamine-beta-hydroxylase in the chromaffin vesicles of the adrenal gland. It is a transmembrane heme protein with the two heme groups being bound to conserved histidine residues. A cytochrome b-561 homologue, termed Dcytb, is an iron-regulated ferric reductase in the duodenal mucosa. Other homologues of these are also likely to be ferric reductases. SDR2 is proposed to be important in regulating the metabolism of iron in the onset of neurodegenerative disorders.
