Recombinant Human Squalene synthase (FDFT1), Truncated

Uniprot Id

P37268

Target Species

Human

Target Name

FDFT1

Target Full Name

Squalene synthase

Target Function

Catalyzes the condensation of 2 farnesyl pyrophosphate (FPP) moieties to form squalene. Proceeds in two distinct steps. In the first half-reaction, two molecules of FPP react to form the stable presqualene diphosphate intermediate (PSQPP), with concomitant release of a proton and a molecule of inorganic diphosphate. In the second half-reaction, PSQPP undergoes heterolysis, isomerization, and reduction with NADPH or NADH to form squalene. It is the first committed enzyme of the sterol biosynthesis pathway.

Target Subcellular Location

Endoplasmic reticulum membrane; Multi-pass membrane protein.

Target Protein Families

Phytoene/squalene synthase family

Target Tissue Specificity

Widely expressed.

Target Research Area

Metabolism

Target Synonyms

DGPT; ERG9; Farnesyl diphosphate farnesyltransferase; Farnesyl-diphosphate farnesyltransferase; FDFT_HUMAN; FDFT1; FPP:FPP farnesyltransferase; SQS; Squalene synthase; Squalene synthetase; SS

Target Background

This gene encodes a membrane-associated enzyme located at a branch point in the mevalonate pathway. The encoded protein is the first specific enzyme in cholesterol biosynthesis, catalyzing the dimerization of two molecules of farnesyl diphosphate in a two-step reaction to form squalene.
