u·biq·ui·tin (y

-b

-t

A polypeptide found in all eukaryotic cells, including plant cells, that participates in a variety of cellular functions including protein degradation.

ubiquitin

[yo̅o̅bik′witin]

a small polypeptide that is involved in histone modification and is a marker for intracellular protein transport and degradation. It is found in all cells of higher organisms.

ubiquitin (yōōˈ·biˑ·kwi·tin),

n a 76-amino acid polypeptide from modification of histones; present in yeast and in most eukaryotic cells.

ubiquitin

heat shock (cell stress) protein present in mammalian cytosol; attaches to other cytosolic proteins and marks them for degradation either by specific proteases or by lysosomal enzymes.
