Crystal Structure of a FYVE-type domain from caspase regulator CARP2

Structural highlights

1y02 is a 1 chain structure with sequence from Human. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum

Function

[RFFL_HUMAN] Has E3 ubiquitin protein ligase activity. Regulates the levels of CASP8 and CASP10 by targeting them for proteasomal degradation. Has anti-apoptotic activity. May bind phosphatidylinositol phosphates.^[1]

Evolutionary Conservation

Publication Abstract from PubMed

The caspase-associated ring proteins (CARP1 and CARP2) are distinguished from other caspase regulators by the presence of a FYVE-type zinc finger domain. FYVE-type domains are divided into two known classes: FYVE domains that specifically bind to phosphatidylinositol 3-phosphate in lipid bilayers and FYVE-related domains of undetermined function. Here, we report the crystal structure of the N-terminal region of CARP2 (44-139) including the FYVE-type domain and its associated helical bundle at 1.7 A resolution. The structure reveals a cramped phosphoinositide binding pocket and a blunted membrane insertion loop. These structural features indicate that the domain is not optimized to bind to phosphoinositides or insert into lipid bilayers. The CARP2 FYVE-like domain thus defines a third subfamily of FYVE-type domains that are functionally and structurally distinct. Structural analyses provide insights into the possible function of this unique subfamily of FYVE-type domains.
