Asymmetric requirement for α-tubulin over β-tubulin
This article's authorsAnnotation by Prachee Avasthi Recommended Reading
This is a super interesting study on the effects of super-stoichiometric alpha or beta tubulin showing budding yeast can tolerate excess alpha but not beta tubulin for normal mictotubule assembly and function. As usual, it is staggering how much we have yet to learn about the fundamentals of cytoskeletal assembly and regulation!

Septins mediate a microtubule-actin crosstalk that enables actin growth on microtubules
This article's authorsAnnotation by Prachee Avasthi Recommended Reading
This is wild! Microtubule-bound septins can capture growing actin filaments for growth along microtubules.

Cell cortex proteome during morphological changes throughout interphase and cell division!

Actin remodelling controls proteasome homeostasis upon stress
This article's authorsAnnotation by Prachee Avasthi Recommended Reading
Very interesting study demonstrating localized translation at yeast endocytic sites of mRNAs for a proteasome assembly-related chaperone during cell stress (rapamycin treatment/TORC1 inhibition). I would be really interested to know if other mRNAs artificially targeted to the same site (which increases translation of this proteasome chaperone) also increases their translation more broadly.

Atypical and distinct microtubule radial symmetries in the centriole and the axoneme ofLecudina tuzetae
This article's authorsAnnotation by Prachee Avasthi Recommended Reading
The 9-fold radial symmetry of centrioles, despite being scaffolded by sas-6 which self assembles in the same pattern, can show different numbers of mictotubules in vivo. This paper show both 8-fold radially symmetric microtubules in centrioles of the parasite Lecudina tuzetae and a reduced number of those 8 that extend into the ciliary axoneme, highlighting other factors that must be involved in regulation of symmetry and selective microtubule extension.

Proteostasis in ice: The role of heat shock proteins and ubiquitin in the freeze tolerance of the intertidal mussel, Mytilus trossulus
This article's authorsAnnotation by Prachee Avasthi Recommended Reading
Getting more interested in cell biological strategies of extremotolerant organisms. Intertidal mussels can survive internal ice formation and sub-zero temps. Interesting result of multiple freeze thaw cycles to allow for heat shock protein expression and ubiquitin conjugation of damaged proteins for recovery between freezes results in reduced mortality in mussels compared to a single freeze.

Unrestrained growth of correctly oriented microtubules instructs axonal microtubule orientation
This article's authorsAnnotation by Prachee Avasthi Recommended Reading
Incredibly interesting! Proximal axons have mixed microtubule polarity and here, they use fly neurons and simulations to suggest that plus end-out microtubules undergo less catastrophe due to a kinesin-1 dependent p150 gradient that stabilizes distal +ends and promotes plus end-out microtubule growth.
