Function
P62 appears to interact with mRNA during transport out of the nucleus. P62 also interacts with a nuclear transport factor (NTF2) protein that is involved in trafficking proteins between cytoplasm and nucleus. Another protein, importin (beta) binds to the helical rod section of p62, which also binds NTF2 suggesting the formation of a higher order gating complex. Karyopherin beta2 (transportin), a riboprotein transporter also interacts with p62. P62 also interacts with nucleoporin-93kDa, and when Nup98 is depleted p62 fails to assemble with nuclear pore complexes. Mutant pores could not dock/transport proteins with nuclear localization signals or M9 import signals.

Famous quotes containing the word function:
“We are thus able to distinguish thinking as the function which is to a large extent linguistic.”
—Benjamin Lee Whorf (18971934)
“Science has fulfilled her function when she has ascertained and enunciated truth.”
—Thomas Henry Huxley (182595)
“As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worryingas a reflex response to demandnever puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.”
—Adam Phillips, British child psychoanalyst. Worrying and Its Discontents, in On Kissing, Tickling, and Being Bored, p. 58, Harvard University Press (1993)
