DDX1: A Versatile RNA Helicase
Tuesday, 18 April 2023
DDX1 (Dead-Box Helicase 1) belongs to the DEAD-Box family of ATP-dependent RNA helicases, whose members are collectively involved in almost all aspects of RNA processing: from transcription to remodeling to degradation. They are named for the central Asp-Glu-Ala-Asp (DEAD) sequence they all possess. The 35 human DEAD-Box proteins comprise the largest family of helicases known.

Investigating RAB2 as a Vesicle Transporter & Autophagy Initiator
Tuesday, 04 April 2023
RAB2 is part of the RAB family of small GTPases that regulate intracellular trafficking of membrane bound vesicles. It is highly conserved in eukaryotes, from C. elegans to humans. These GTPases influence the creation, movement, attachment, fusion, and destiny of vesicles originating in the endoplasmic reticulum (ER)/Golgi systems. Like other members of its family, RAB2

Is PARP1 a Hero or Villain?
Tuesday, 07 March 2023
Not counting histones, PARP1 [Poly(ADP-ribose) Polymerase 1] is the most abundant nuclear protein in mammalian cells. While principally known for its role in various types of DNA repair, recent work expanded it’s repertoire to include genome stability maintenance, chromatin remodeling, DNA methylation/gene expression, cellular differentiation, and cell survival modulation via NAD+/ATP regulation.1 It performs Poly(ADP-ribosyl)ation
