Kindlins are FERM-containing cytoplasmic proteins that regulate integrin-mediated
cell-cell and cell-extracellular matrix (ECM) attachments. Kindlin-3 is expressed
in hematopoietic cells, platelets, and endothelial cells. Studies have shown that
kindlin-3 stabilizes cell adhesion mediated by ß1, ß2, and ß3 integrins. Apart
from integrin cytoplasmic tails, kindlins are known to interact with other
cytoplasmic proteins. Here we demonstrate that kindlin-3 can associate with
ribosome via the receptor for activated-C kinase 1 (RACK1) scaffold protein based
on immunoprecipitation, ribosome binding, and proximity ligation assays. We show
that kindlin-3 regulates c-Myc protein expression in the human chronic myeloid
leukemia cell line K562. Cell proliferation was reduced following siRNA reduction
of kindlin-3 expression and a significant reduction in tumor mass was observed in
xenograft experiments. Mechanistically, kindlin-3 is involved in integrin
?5ß1-Akt-mTOR-p70S6K signaling; however, its regulation of c-Myc protein
expression could be independent of this signaling axis.
