Descriptions

ANP32A(I1<sup>PP2A</sup>) regulates PP2A activity by functioning as a non-competitive inhibitor of this enzyme. PP2A is a major regulator of the phosphorylation of Tau. The activity of PP2A is compromised in Alzheimer's disease brain. ANP32A has an autoinhibitory domain that negatively affects the interaction of ANP32A with PP2Ac and its ability to modulate the PP2A activity, which lies within amino acid residues 121-163. The inhibitory role of the autoinhibitory region might be regulated through the phosphorylation of Ser-158 or both Ser-158 and Ser-204 by casein kinase II. The autoinhibition is disrupted by C-terminal region.

4 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
endoplasmic reticulum 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).
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
perinuclear region of cytoplasm Cytoplasm situated near, or occurring around, the nucleus.

1 GO annotations of molecular function

Name Definition
histone binding Binding to a histone, any of a group of water-soluble proteins found in association with the DNA of eukaryotic or archaeal chromosomes. They are involved in the condensation and coiling of chromosomes during cell division and have also been implicated in gene regulation and DNA replication. They may be chemically modified (methylated, acetlyated and others) to regulate gene transcription.

2 GO annotations of biological process

Name Definition
nucleocytoplasmic transport The directed movement of molecules between the nucleus and the cytoplasm.
regulation of apoptotic process Any process that modulates the occurrence or rate of cell death by apoptotic process.
