CC -!- FUNCTION: Not known. One of the major polypeptides produced on heat
CC shock.
CC -!- SUBUNIT: Present in large complexes.
CC -!- INTERACTION:
CC P15992; P15992: HSP26; NbExp=2; IntAct=EBI-8555, EBI-8555;
CC -!- DEVELOPMENTAL STAGE: Expressed during the entry into stationary phase
CC resulting from glucose limitation.
CC -!- INDUCTION: By heat shock, and under other conditions of stress, such as
CC increased salt concentration and starvation.
CC -!- MISCELLANEOUS: Present with 19300 molecules/cell in log phase SD
CC medium. {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the small heat shock protein (HSP20) family.
CC {ECO:0000255|PROSITE-ProRule:PRU00285}.
