Cell. Proteomics 13:372-387(2014). CC -!- FUNCTION: Small heat shock protein which functions as a molecular CC chaperone probably maintaining denatured proteins in a folding- CC competent state. Plays a role in stress resistance and actin CC organization (PubMed:17661394). Through its molecular chaperone CC activity may regulate numerous biological processes including the CC phosphorylation and the axonal transport of neurofilament proteins (By CC similarity). {ECO:0000250|UniProtKB:P04792, CC ECO:0000269|PubMed:17661394}. CC -!- SUBUNIT: Homooligomer. Homodimer; becomes monomeric upon activation. CC Heterooligomer; with HSPB6. Associates with alpha- and beta-tubulin (By CC similarity). Interacts with TGFB1I1 (PubMed:11546764). Interacts with CC CRYAB (By similarity). Interacts with HSPB8 (PubMed:11342557). CC Interacts with HSPBAP1 (PubMed:10751411). CC {ECO:0000250|UniProtKB:P04792, ECO:0000269|PubMed:10751411, CC ECO:0000269|PubMed:11342557, ECO:0000269|PubMed:11546764}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P04792}. Nucleus CC {ECO:0000250|UniProtKB:P04792}. Cytoplasm, cytoskeleton, spindle CC {ECO:0000250|UniProtKB:P04792}. Note=Cytoplasmic in interphase cells. CC Colocalizes with mitotic spindles in mitotic cells. Translocates to the CC nucleus during heat shock and resides in sub-nuclear structures known CC as SC35 speckles or nuclear splicing speckles. CC {ECO:0000250|UniProtKB:P04792}. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=3; CC Comment=Additional isoforms seem to exist.; CC Name=A; CC IsoId=P14602-1; Sequence=Displayed; CC Name=B; CC IsoId=P14602-2; Sequence=VSP_002422; CC Name=C; CC IsoId=P14602-3; Sequence=VSP_002423; CC -!- PTM: Phosphorylated upon exposure to protein kinase C activators and CC heat shock (By similarity). Phosphorylation by MAPKAPK2 and MAPKAPK3 in CC response to stress dissociates HSPB1 from large small heat-shock CC protein (sHsps) oligomers and impairs its chaperone activity and CC ability to protect against oxidative stress effectively. CC Phosphorylation by MAPKAPK5 in response to PKA stimulation induces F- CC actin rearrangement (PubMed:1332886, PubMed:1860870, PubMed:21575178, CC PubMed:8093612). {ECO:0000250|UniProtKB:P04792, CC ECO:0000269|PubMed:1332886, ECO:0000269|PubMed:1860870, CC ECO:0000269|PubMed:21575178, ECO:0000269|PubMed:8093612}. CC -!- DISRUPTION PHENOTYPE: Mice are viable and fertile with no apparent CC morphological abnormalities in tissues under physiological conditions. CC {ECO:0000269|PubMed:17661394}. CC -!- SIMILARITY: Belongs to the small heat shock protein (HSP20) family. CC {ECO:0000255|PROSITE-ProRule:PRU00285}.
