Minor Spliceosome
The minor spliceosome is a ribonucleoprotein complex that catalyses the removal (splicing) of an atypical class of spliceosomal introns (U12-type) from eukaryotic messenger RNAs in plant, insects, vertebrates and some fungi (Rhizopus oryzae). This process is called noncanonical splicing, as opposed to U2-dependent canonical splicing. U12-type introns represent less than 1% of all introns in human cells. However they are found in genes performing essential cellular functions.

Famous quotes containing the word minor:
“A certain minor light may still
Leap incandescent
Out of kitchen table or chair
As if a celestial burning took
Possession of the most obtuse objects now and then—”
—Sylvia Plath (1932–1963)
