Rabbit anti-Human POR Polyclonal Antibody

Uniprot Id

P16435

Target Species

Human

Target Name

POR

Target Full Name

NADPH--cytochrome P450 reductase

Target Function

This enzyme is required for electron transfer from NADP to cytochrome P450 in microsomes. It can also provide electron transfer to heme oxygenase and cytochrome B5.

Target Involvement

Antley-Bixler syndrome, with genital anomalies and disordered steroidogenesis (ABS1); Disordered steroidogenesis due to cytochrome P450 oxidoreductase deficiency (DISPORD)

Target Subcellular Location

Endoplasmic reticulum membrane; Single-pass membrane protein; Cytoplasmic side.

Target Protein Families

NADPH--cytochrome P450 reductase family; Flavodoxin family; Flavoprotein pyridine nucleotide cytochrome reductase family

Target Synonyms

CPR; CYPOR; Cytochrome p450 oxidoreductase; DKFZp686G04235; FLJ26468; NADPH Cytochrome P450 Reductase; NADPH dependent cytochrome P450 reductase; NADPH--cytochrome P450 reductase; NCPR_HUMAN; P450 (cytochrome) oxidoreductase; P450 Cytochrome Oxidoreductase; P450R; por

Target Background

This gene encodes an endoplasmic reticulum membrane oxidoreductase that is essential for multiple metabolic processes, including reactions catalyzed by cytochrome P450 proteins for metabolism of steroid hormones, drugs and xenobiotics. The encoded protein has a flavin adenine dinucleotide (FAD)-binding domain and a flavodoxin-like domain which bind two cofactors, FAD and FMN, that allow it to donate electrons directly from NADPH to all microsomal P450 enzymes. Mutations in this gene cause a complex set of disorders, including apparent combined P450C17 and P450C21 deficiency, amenorrhea and disordered steroidogenesis, congenital adrenal hyperplasia and Antley-Bixler syndrome, that resemble those caused by defects in steroid metabolizing enzymes such as aromatase, 21-hydroxylase, and 17 alpha-hydroxylase.
