Positive selection analyses identify a single WWE domain residue that shapes ZAP into a more potent restriction factor against alphaviruses.

open access: yesPLoS Pathogens
The host interferon pathway upregulates intrinsic restriction factors in response to viral infection. Many of them block a diverse range of viruses, suggesting that their antiviral functions might have been shaped by multiple viral families during ...

Proteogenomic reprogramming to a functional human blastomere-like stem cell state via a PARP-DUX4 regulatory axis

open access: yesCell Reports
Summary: Here, we show that conventional human pluripotent stem cells cultured with non-specific tankyrase-PARP1-inhibited conditions underwent proteogenomic reprogramming to functional blastomere-like tankyrase/PARP inhibitor-regulated naive stem cells (

Rewriting the viral script: post-translational modifications orchestrating SARS-CoV-2 pathogenesis and immune evasion

open access: yesFrontiers in Microbiology
SARS-CoV-2 reprograms host cell biology not solely through its genomic content but also through a sophisticated arsenal of post-translational modifications (PTMs) that modulate viral protein function, host signaling networks, and immune responses ...

Zebrafish arl6ip1 is required for neural crest development during embryogenesis.

open access: yesPLoS ONE, 2012
BackgroundAlthough the embryonic expression pattern of ADP ribosylation factor-like 6 interacting protein 1 (Arl6ip1) has been reported, its function in neural crest development is unclear.Methods/principal findingsWe found that knockdown of Arl6ip1 ...

Mapping genetic interactions in cancer: a road to rational combination therapies. [PDF]

open access: yes, 2019
The discovery of synthetic lethal interactions between poly (ADP-ribose) polymerase (PARP) inhibitors and BRCA genes, which are involved in homologous recombination, led to the approval of PARP inhibition as a monotherapy for patients with BRCA1/2 ...

The ubiquitin E3/E4 ligase, UBE4A, fine-tunes protein ubiquitylation and accumulation at sites of DNA damage facilitating double-strand break repair [PDF]

open access: yes, 2018
Double-strand breaks (DSBs) are critical DNA lesions that robustly activate the elaborate DNA damage response (DDR) network. We identified a critical player in DDR fine-tuning - the E3/E4 ubiquitin ligase, UBE4A.

The importance of Poly(ADP-Ribose) Polymerase as a sensor of unligated Okazaki fragments during DNA replication [PDF]

open access: yes, 2018
Poly(ADP-ribose) is synthesized by PARP enzymes during the repair of stochastic DNA breaks. Surprisingly, however, we show that most if not all endogenous poly(ADP-ribose) is detected in normal S phase cells at sites of DNA replication. This S phase poly(
