Opis

Opis ogólny

Microtubules are cytoskeletal filaments composed of of alpha-/beta-tubulin heterodimers that self-assemble head-to-tail to form protofilaments and laterally to form a hollow tube. Various post-translational modifications (PTMs), including acetylation, polyglutamylation, polyglycylation, detyrosination, phosphorylation, and palmitoylation, can regulate the polymerization properties of tubulins and/or their interactions with microtubule associated proteins (MAPs) and motor proteins. A subset of cytoplasmic microtubules and microtubules in the spindle, axon, and cilia are known to contain alpha-tubulin acetylated via the epsilon-amino group of Lysine-40 (K40). The GNAT lysine acetyltransferase family member MEC-17 (or alpha-tubulin acetyltransferase/alphaTAT) catalyzes K40 acetylation, while HDAC6 and sirtuin2 (SIRT2) are known to catalyze tubulin deacetylation. Experimental evidences indicate that K40 acetylation primes alpha-tubulin for further PTM(s), which cannot be reversed by later deactylation of K40ac. Subsequently, the acetylated and deacetylated alpha-tubulin in native microtubules are structurally distinct from that of unacetylated alpha-tubulin (never before has its K40 acetylated).

Specyficzność

Experimental evidences indicate that the acetylated and deacetylated α-tubulin in native microtubules are structurally distinct from that of unacetylated α-tubulin, and that clone 6-11B-1 recognizes acetylated and deacetylated α-tubulin, but not unacetylated (never acetylated) α-tubulin. While 6-11B-1 immunostaining pattern resembles that of acetyl-Lys40 antibodies on normal cylcling cells, caution must be taken when interpreting immunostaining results using this mAb on cells subjected to tubulin deacetylation manipulations by exogenous deacetylase expression or via chemical means.
