Two polyisoprenoid families with dominating C80 and C110 indicating the activity of both yeast Z-prenyltransferases Rer2p and Srt1p, respectively. The family of longer chain dolichols appearing in the stationary growth phase contains dolichols with even more than 50 isoprene units exhibiting monotonically decreasing amounts with increasing chain lengths. The family of shorter chain dolichols is characteristic of the Rer2p products synthesized during the logarithmic growth phase of yeast. It forms a well-defined family of dolichols with 1318 isoprene residues with a certain level of longer dolichols composed of up to 24 isoprene units

metabolism
necessity of both dehydrodolichol diphosphate synthase, DHDDS or hCIT, and Nogo-B receptor, NgBR, for dolichol biosynthesis. Single subunit cis-PTases catalyze the condensation reactions of isopentenyl diphosphate (IPP) with farnesyl diphosphate (FPP) to synthesize linear polyprenyl diphosphate with specific chain lengths.

key enzyme in dolichol biosynthesis, the identity of the cloned enzyme is confirmed by functional complementation of a yeast mutant strain defective in dehydrodolichyl-diphosphates synthase activity, Arabidopsis thaliana enzyme catalyzes the synthesis of dehydrodolichyl-diphosphates with chain lengths similar to those found in yeast
physiological function
over-expression of SRT1 suppresses the growth and glycosylation defects of rer2. SRT1 has only a minor contribution to total cis-prenyltransferase activity under normal conditions
physiological function
RER2 encodes a key enzyme of dolichol synthesis
physiological function
cis-prenyltransferase is committed to the synthesis of dolichol, the Nogo-B receptor, NgBR, is a subunit required for dolichol synthesis in humans, essential role of NgBR in dolichol synthesis and protein glycosylation. NgBR as a protein interacts with reticulon 4B, also called Nogo-B
physiological function
cis-prenyltransferase is committed to the synthesis of dolichol, the Nogo-B receptor, NgBR, is a subunit required for dolichol synthesis in mice, essential role of NgBR in dolichol synthesis and protein glycosylation
physiological function
cis-prenyltransferase Rer2 is required for protein glycosylation, cell wall integrity and hypha formation. Dolichols are essential not only for protein glycosylation and cell wall integrity but also for growth and development of Candida albicans
physiological function
the SlCPT3 and SlCPTBP proteins interact to form a functional dolichol synthase

R290H
a naturally occuring NgBR R290H mutation leading to congenital disorder of glycosylation. cis-PTase activity and mannose incorporation into proteins is markedly lower in NgBR R290H fibroblasts compared to control, the NgBR R290H mutant is a loss of function mutation that affects cis-PTase function of NgBR without disrupting complex formation with hCIT or Nogo-B. The reduced cis-PTase activity in fibroblasts is manifested as altered dolichol profiles in the urine or serum as assessed by mass spectrometry of all carriers of the R290H mutation, phenotype, overview

generation of RNAi-mediated knockdown of SlCPT3 expression in plants, SlCPT3 gene expression and also polyisoprenoid contents are reduced by approximately 60% and 40%, respectively. Although transgenic plantlets are recovered that exhibit a higher degree of SlCPT3 knockdown, they do snot survive to maturity.
