A Role For The Poly-Asparagine Repeat In The Plasmodium Histone Acetyltransferase, Pfgcn5, Kelly Rubiano, Aaron Morris, Francisca D L Vitorino, Jasper Travis, Benjamin A Garcia, Sumit Mukherjee, Daniel E Goldberg

2020-Current year OA Pubs

Plasmodium falciparum possesses one of the most AT-rich genomes in nature (80.6%). A consequence is an asparagine-rich proteome. A quarter of P. falciparum proteins possess poly-asparagine repeats that can extend more than 100 residues. The role of these repeats has remained a mystery in the biology of this parasite. Here, we report that the poly-asparagine repeat-containing Nterminus of the histone acetyltransferase PfGCN5 associates with the C-terminal catalytic domain after cleavage in the nucleus. Deletion of the repeat destabilizes the N-terminal polypeptide, leading to impaired parasite development and growth, particularly under stress conditions. Using high-resolution mass spectrometry and western blotting analysis, …

Fragile Hope And The Cultural Life Of Law, Shefali Jain Jun 2026

Fragile Hope And The Cultural Life Of Law, Shefali Jain

Socio-Legal Review

This review of Sandhya Fuchs’ Fragile Hope: Seeking Justice for Hate Crimes in India (Stanford University Press 2024) highlights that the book makes a genuinely original ethnographic and conceptual contribution to caste studies and hate crime scholarship. At the same time, the essay argues that there are three limitations to its framework that require greater engagement: the book’s failure to engage with the legal consciousness tradition in socio-legal scholarship, an underdeveloped account of “legal meliorism,” and an unresolved tension between the book’s stated commitment to victim-centred analysis and its ethnographic evidence that frequently discusses movement-level aspirations.
