Look, I'm so sorry, couldn't find any info on this. But tubulin is a protein ( heterodimer) formed by  α  and  β  subunits. Generatis the cytoskeleton. So, I hope you can get something from that. Sorry

If you know what kinds of proteins are synthesized attached to the ER, then you should be able to answer this question.

But, do you know which ones, @jc7 ?

Integral membrane proteins (proteins that cross the membrane) and secreted proteins are synthesized in the rough ER. Tubulin is neither an integral membrane protein nor a secreted protein
