LAP1 adopts an AAA+ like fold that, while unable to bind nucleotide, can enhance ATPase activity in the neighboring TorsinA protomer in an unusual heterohexameric ring, via an arginine finger.
A new family of sterol-specific lipid transfer proteins has been found that anchors in the endoplasmic reticulum; some of these proteins stretch across membrane contacts and mediate sterol traffic from the plasma membrane.
The C. elegans ninein homolog NOCA-1 is important for the assembly of non-centrosomal microtubule arrays required for embryo production, nuclear positioning and larval development.
PHF13 interacts with transcriptional complexes containing RNA polymerase II to recruit/stabilize them at H3K4me2/3 containing active or bivalent promoters.

A straightforward, rapid and generalizable strategy uses modified nanobodies to convert intracellular protein detection into desired biological activities in cells and animals.
A fully synthetic library of humanized single domain antibodies yields in vitro high affinity antibodies usable in cell biology and translational projects.
