Sažetak
Tubulin polymerization promoting proteins (TPPPs) constitute a eukaryotic protein family. There are three TPPP paralogs in the human genome, denoted as TPPP1–TPPP3. TPPP1 and TPPP3 are intrinsically unstructured proteins (IUPs) that bind and polymerize tubulin and stabilize microtubules, but TPPP2 does not. Vertebrate TPPPs originated from the ancient invertebrate TPPP by two-round whole- genome duplication ; thus, whether the tubulin/microtubule binding function of TPPP1 and TPPP3 is a newly acquired property or was present in the invertebrate orthologs (generally one TPPP per species) has been an open question. To answer this question, we investigated a TPPP from a simple and early branching animal, the sponge Suberites domuncula. Bioinformatics, biochemical, immunochemical, spectroscopic, and electron microscopic data showed that the properties of the sponge protein correspond to those of TPPP1 ; namely, it is an IUP that strongly binds tubulin and induces its polymerization, proving that these features of animal TPPPs have been evolutionarily conserved.
