Small heat shock protein which functions as a molecular chaperone probably maintaining denatured proteins in a folding-competent state. Seems to have versatile functions in various biological processes. Plays a role in regulating muscle function such as smooth muscle vasorelaxation and cardiac myocyte contractility. May regulate myocardial angiogenesis implicating KDR. Overexpression mediates cardioprotection and angiogenesis after induced damage. Stabilizes monomeric YWHAZ thereby supporting YWHAZ chaperone-like activity.By similarity1 Publication

Homodimer (PubMed:19646995). Small heat shock proteins form high molecular mass oligomers containing variable number of monomers; these oligomers display a very flexible quaternary structure easily exchanging their subunits. Heterooligomer with HSPB1; formed through oligomerization of HSPB1:HSBP6 dimers; subunit exchange leads to formation of at least two different heterooligomeric complexes, differing in variable quantities of HSPB1 and HSPB6 homodimers in addition to HSPB1:HSPB6 heterodimers. Heterooligomer with CRYAB; large heterooligomers consist of CRYAB homodimers and HSPB5:HSPB6 heterodimers but lacking HSPB6 homodimers.

Interacts with BAG3.

Interacts (phosphorylated) with YWHAZ.

Interacts with PDE4A and PDE4D; required for maintenance of the non-phosphorylated state of HSPB6 under basal conditions.

Interacts with KDR.

Interacts with PRKD1 (By similarity).

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
