  Domain Name: ACD_HspB8_like
Alpha-crystallin domain (ACD) found in mammalian 21.6 KDa small heat shock protein (sHsp) HspB8, also denoted as Hsp22 in humans, and similar proteins. sHsps are molecular chaperones that suppress protein aggregation and protect against cell stress, and are generally active as large oligomers consisting of multiple subunits. A chaperone complex formed of HspB8 and Bag3 stimulates degradation of protein complexes by macroautophagy. HspB8 also forms complexes with Hsp27 (HspB1), MKBP (HspB2), HspB3, alphaB-crystallin (HspB5), Hsp20 (HspB6), and cvHsp (HspB7). These latter interactions may depend on phosphorylation of the respective partner sHsp. HspB8 may participate in the regulation of cell proliferation, cardiac hypertrophy, apoptosis, and carcinogenesis. Point mutations in HspB8 have been correlated with the development of several congenital neurological diseases, including Charcot Marie tooth disease and distal motor neuropathy type II.
No pairwise interactions are available for this conserved domain.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
