Function

Key enzyme in the cholesterol biosynthesis pathway. Catalyzes the cyclization of (S)-2,3 oxidosqualene to lanosterol, a reaction that forms the sterol nucleus (PubMed:14766201, PubMed:26200341, PubMed:7639730). Through the production of lanosterol may regulate lens protein aggregation and increase transparency (PubMed:26200341).

Involvement in disease

Cataract 44

CTRCT44

An opacification of the crystalline lens of the eye that frequently results in visual impairment or blindness. Opacities vary in morphology, are often confined to a portion of the lens, and may be static or progressive. In general, the more posteriorly located and dense an opacity, the greater the impact on visual function.

None

The disease is caused by variants affecting the gene represented in this entry.

Hypotrichosis 14

HYPT14

A form of hypotrichosis, a condition characterized by the presence of less than the normal amount of hair and abnormal hair follicles and shafts, which are thin and atrophic. The extent of scalp and body hair involvement can be very variable, within as well as between families. HYPT14 is an autosomal recessive form characterized by sparse to absent lanugo-like scalp hair, sparse and brittle eyebrows, and sparse eyelashes and body hair.

None

The disease is caused by variants affecting the gene represented in this entry.

Alopecia-intellectual disability syndrome 4

APMR4

An autosomal recessive disorder characterized by alopecia universalis, scaly skin, mild to severe intellectual disability, delayed or absent speech, and motor delay.

None

The disease is caused by variants affecting the gene represented in this entry.

Pathway

Terpene metabolism; lanosterol biosynthesis; lanosterol from farnesyl diphosphate: step 3/3.

Sequence similarities

Belongs to the terpene cyclase/mutase family.

Tissue specificity

Widely expressed. Expressed in the hair bulb, the outer root sheath and hair matrix of the hair follicle epithelium. Also detected in dermal papilla, epidermis, sweat glands, sebaceous glands, and blood vessels.

Cellular localization

  • Endoplasmic reticulum membrane
  • Peripheral membrane protein

Alternative names
