Summary: The protein encoded by this gene is a member of the Fe65 protein family. It is an adaptor protein localized in the nucleus. It interacts with the Alzheimer's disease amyloid precursor protein (APP), transcription factor CP2/LSF/LBP1 and the low-density lipoprotein receptor-related protein. APP functions as a cytosolic anchoring site that can prevent the gene product's nuclear translocation. This encoded protein could play an important role in the pathogenesis of Alzheimer's disease. It is thought to regulate transcription. Also it is observed to block cell cycle progression by downregulating thymidylate synthase expression. Multiple alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Mar 2012]

FE65 is found to activate ELMO1 by diminishing ELMO1 intramolecular autoinhibitory interaction and to promote the targeting of ELMO1 to the plasma membrane, where Rac1 is activated. We also show that FE65, ELMO1, and DOCK180 form a tripartite complex

Fe65 is an adaptor protein involved in both processing and signaling of the Alzheimer-associated amyloid-beta precursor protein, APP. Here, the subcellular localization was further investigated using TAP-tagged Fe65 constructs expressed in human neuroblastoma cells. Our results indicate that PTB2 rather than the WW domain is important for the nuclear localization of Fe65.

This encoded isoform (b) is widely expressed in all non-neuronal cells but is not expressed in differentiated neurons.

NR_047512.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (11) uses an alternate acceptor splice site in the 3' terminal exon compared to variant 1. The resulting open reading frame (ORF) has no stop codon, and no other ORF is supported. Therefore, this is likely to be a non-coding transcript and subject to degradation via the nonstop-mediated mRNA surveillance pathway.
