It has been suggested that pICln, which occurs in all three precursor complexes but is absent in the mature snRNPs, acts as a specialized chaperone, preventing premature assembly of Sm proteins.
Suxeriuse que pICln, que aparece nos tres complexos precursores pero está ausente nas snRNP maduras, funciona como unha chaperona especializada, impedindo a ensamblaxe prematura das proteínas Sm.
