FunFam 22: Phosphatidylinositol 4-kinase stt4

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 4 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
Autophagy of mitochondrion GO:0000422
The autophagic process in which mitochondria are delivered to the vacuole and degraded in response to changing cellular conditions.
2 P37297 (/IMP) P37297 (/IMP)
Macroautophagy GO:0016236
The major inducible pathway for the general turnover of cytoplasmic constituents in eukaryotic cells, it is also responsible for the degradation of active cytoplasmic enzymes and organelles during nutrient starvation. Macroautophagy involves the formation of double-membrane-bounded autophagosomes which enclose the cytoplasmic constituent targeted for degradation in a membrane-bounded structure. Autophagosomes then fuse with a lysosome (or vacuole) releasing single-membrane-bounded autophagic bodies that are then degraded within the lysosome (or vacuole). Some types of macroautophagy, e.g. pexophagy, mitophagy, involve selective targeting of the targets to be degraded.
2 P37297 (/IMP) P37297 (/IMP)
Cortical actin cytoskeleton organization GO:0030866
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of actin-based cytoskeletal structures in the cell cortex, i.e. just beneath the plasma membrane.
2 P37297 (/IMP) P37297 (/IMP)
Phosphatidylinositol phosphorylation GO:0046854
The process of introducing one or more phosphate groups into a phosphatidylinositol, any glycerophosphoinositol having one phosphatidyl group esterified to one of the hydroxy groups of inositol.
2 P37297 (/IDA) P37297 (/IDA)
Phosphatidylinositol phosphorylation GO:0046854
The process of introducing one or more phosphate groups into a phosphatidylinositol, any glycerophosphoinositol having one phosphatidyl group esterified to one of the hydroxy groups of inositol.
2 P37297 (/IGI) P37297 (/IGI)
Regulation of fungal-type cell wall organization GO:0060237

2 P37297 (/IMP) P37297 (/IMP)
Phosphatidylethanolamine biosynthetic process GO:0006646
