Sterol is an organic compound [1] with formula C 17 H 28 O , whose molecule is derived from that of gonane by replacement of a hydrogen atom on C3 position by a hydroxyl group.
Proteolytic cleavage frees it to move through the cytoplasm to the nucleus. Once in the nucleus, SREBP can bind to specific DNA sequences (the sterol regulatory elements or SREs) that are found in the control regions of the genes that encode enzymes needed to make lipids. This binding to DNA leads to the increased transcription of the target genes.
A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.

Sterol carrier proteins (also known as nonspecific lipid transfer proteins) is a family of proteins that transfer steroids and probably also phospholipids and gangliosides between cellular membranes. These proteins are different from plant nonspecific lipid transfer proteins but structurally similar to small proteins of unknown function from ...

Concretely, they constitute a family of sterol and phosphoinositide binding and transfer proteins in eukaryotes [2] that are conserved from yeast to humans. They are lipid-binding proteins implicated in many cellular processes related with oxysterol , including signaling, vesicular trafficking, lipid metabolism, and nonvesicular sterol transport.
