'''THE CRYSTAL STRUCTURE OF THE TUMOR SUPRESSOR PROTEIN PP32 (ANP32A):STRUCTURAL INSIGHTS INTO THE ANP32 FAMILY OF PROTEINS'''<br />


==Overview==
==The crystal Structure of the tumor supressor protein pp32 (Anp32a) :structural insights into the Anp32 family of proteins==
The tumor suppressor protein pp32 is highly overexpressed in many cancers, of the breast and prostate, and has also been implicated in the, neurodegenerative disease spinocerebellar ataxias type 1 (SCA1). Pp32 is a, multifunctional protein that is involved in the regulation of, transcription, apoptosis, phosphorylation, and cell cycle progression, the, latter through its association with the hyperphosphorylated form of the, retinoblastoma tumor suppressor. We have determined the structure of an, N-terminal pp32 fragment comprising a capped leucine-rich repeat (LRR), domain, which provides insight into the structural and biochemical, properties of the pp32 (Anp32) family of proteins.

== Function ==
[https://www.uniprot.org/uniprot/AN32A_HUMAN AN32A_HUMAN] Implicated in a number of cellular processes, including proliferation, differentiation, caspase-dependent and caspase-independent apoptosis, suppression of transformation (tumor suppressor), inhibition of protein phosphatase 2A, regulation of mRNA trafficking and stability in association with ELAVL1, and inhibition of acetyltransferases as part of the INHAT (inhibitor of histone acetyltransferases) complex. Plays a role in E4F1-mediated transcriptional repression.<ref>PMID:15642345</ref> <ref>PMID:10400610</ref> <ref>PMID:11360199</ref> <ref>PMID:17557114</ref>
