FunFam 54: StAR-related lipid transfer protein 4

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 5 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

GO Term Annotations Evidence
Positive regulation of cholesterol esterification GO:0010873
Any process that increases the frequency, rate or extent of cholesterol esterification. Cholesterol esterification is the lipid modification process in which a sterol ester is formed by the combination of a carboxylic acid (often a fatty acid) and cholesterol. In the blood this process is associated with the conversion of free cholesterol into cholesteryl ester, which is then sequestered into the core of a lipoprotein particle.

Positive regulation of cholesterol esterification GO:0010873
Any process that increases the frequency, rate or extent of cholesterol esterification. Cholesterol esterification is the lipid modification process in which a sterol ester is formed by the combination of a carboxylic acid (often a fatty acid) and cholesterol. In the blood this process is associated with the conversion of free cholesterol into cholesteryl ester, which is then sequestered into the core of a lipoprotein particle.
1 Q99JV5 (/ISO)
Cholesterol transport involved in cholesterol storage GO:0010879
The directed movement of cholesterol into cells that is part of their accumulation and maintenance.
1 Q96DR4 (/IDA)
Cholesterol transport involved in cholesterol storage GO:0010879
The directed movement of cholesterol into cells that is part of their accumulation and maintenance.
1 Q99JV5 (/ISO)
Intracellular cholesterol transport GO:0032367
The directed movement of cholesterol, cholest-5-en-3-beta-ol, within cells.
1 Q96DR4 (/IDA)
Intracellular cholesterol transport GO:0032367
The directed movement of cholesterol, cholest-5-en-3-beta-ol, within cells.

A lipid modification process in which a sterol ester is formed by the combination of a carboxylic acid (often a fatty acid) and cholesterol. In the blood this process is associated with the conversion of free cholesterol into cholesteryl ester, which is then sequestered into the core of a lipoprotein particle.
1 Q99JV5 (/IDA)
Cholesterol import GO:0070508
The directed movement of cholesterol into a cell or organelle.

Cholesterol import GO:0070508
The directed movement of cholesterol into a cell or organelle.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of bile acids.
1 Q96DR4 (/IDA)
Positive regulation of bile acid biosynthetic process GO:0070859

GO Term Annotations Evidence
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 Q96DR4 (/IDA)
Mitochondrion GO:0005739
A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
1 Q99JV5 (/TAS)
Endoplasmic reticulum GO:0005783
The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
