abstract = {The armadillo repeat protein ARVCF is a component of
adherens junctions. Similar to related proteins, such as
p120-catenin and β-catenin, with known signaling functions,
localization studies indicate a cytoplasmic and a nuclear
pool of ARVCF. We find that ARVCF interacts with different
proteins involved in mRNA-processing: the splicing factor
SRSF1 (SF2/ASF), the RNA helicase p68 (DDX5), and the
heterogeneous nuclear ribonucleoprotein hnRNP H2. All three
proteins bind to ARVCF in an RNA-independent manner.
Furthermore, ARVCF occurs in large RNA-containing complexes
that contain both spliced and unspliced mRNAs of
housekeeping genes. By domain analysis, we show that
interactions occur via the ARVCF C terminus. Overexpression
of ARVCF, p68, SRSF1, and hnRNP H2 induces a significant
increase in splicing activity of a reporter mRNA. Upon
depletion of ARVCF followed by RNA sequence analysis,
several alternatively spliced transcripts are significantly
changed. Therefore, we conclude that nuclear ARVCF
influences splicing of pre-mRNAs. We hypothesize that ARVCF
is involved in alternative splicing, generating proteomic
diversity, and its deregulation may contribute to diseased
states, such as cancer and neurological disorders.},
