Awesome work!!!

We found that endogenous ligand for GPR139 is opioid peptide dynorphin. With this, GPR139 may not be an orphan any more but the 5th opioid receptor. Heavy lift by talented Xiaona Li with great thanks to all who contributed! https://t.co/OabhjeWV1q

Wow!!!
Excited to present our preprint on the structure-function relationship of anaphylatoxin complement receptors. A casual number of 19 structures deciphering ligand recognition mechanisms, G protein/arrestin and species specific signaling. Check it out! https://t.co/asIcSp9gF6

We have innovated design of templates for CRISPR/Cas9 editing which allows efficient introduction of epitope tags in vivo. It is a simple hack which we hope to be broadly useful. Work by talented graduate student Chuanping Zhao. https://t.co/vtULnZpYKA

The ON/OFF dichotomy is fundamental to visual processing. In a new study led by Flori Soto, we identify a conserved molecular mechanism establishing the OFF pathway. https://t.co/is4NEvc0ME

Our latest on GPCR function in the brain. We report that glutamate receptor mGlu4 needs to be properly positioned at synapses of cholinergic interneurons in NAc by cell adhesion molecule ELFN1 to regulate opioid reward. https://t.co/edTSBmWMfS

A popular FDA-approved drug to treat hypertension, hydralazine works, at least in part, by modulating RGS proteins! Honored to be a part of a collaborative team led by @MegaMatthewsLab! https://t.co/aVVqDcsgy4

Excited to share our latest on ELFN1 mechanisms, a dysfunction of which leads to a devastating neurodevelopmental disorder. Swan song of @GPCRHenry. #GPCR , #Elfn1, @jbiolchem

Happy to introduce DeFrND: designer peptide scaffolds to enable detergent-free reconstitution of membrane proteins with native lipids into nanodiscs for biochemical and structural studies. Let me know if you would like to try it. https://t.co/DhxKsIXUGE

Membrane scaffold proteins-based nanodiscs (NDs) have facilitated unprecedented structural and biophysical analysis of membrane proteins in a near-native lipid environment. However, successful...

As shown recently a single point mutation in G protein alpha subunit yields a stable complex without the use of stabilizing nanobodies! https://t.co/OM941o5cG5

Spot on!
A few postdocs asked me to read over their job applications. Here’s a few bits of advice: 🧵 /10 1. If any advice doesn’t ring true for you, discard it (including this!) 2. People on the search committee are keen to welcome a colleague, they aren’t looking to take you down

This is a must read masterclass in sensory circuit dissection and really cool behavioral adaptation!
In a new study led by @mike_fitz23, we describe a pupillary contrast response in mice and humans, which senses temporal contrast to enhance spatial contrast in the retinal image and increase visual acuity. We decipher the underlying neural mechanisms.

Frizzled receptors are so cool. Consolidated model of GPCR realm with scaffolding signalosome.
Check out our new review in TiPS "Frizzleds act as dynamic pharmacological entities" written with the postdocs in the team: @GraetzLukas @PKozielewicz @MagdalenaScharf @JanVo12 and twitterless Julien Bous. https://t.co/pzvQbEZTQ3

This is a phenomenal paper! Very easy to read and advance is mesmerizing. Highly recommend to folks interested in orphan receptors and their role in totally new biology.
In the latest issue! A gut-derived hormone regulates cholesterol metabolism

Welcome, Ezgi @ezgi_hsuleyman ! Looking forward to working with you!
Welcome @ezgi_hsuleyman, Ph.D., who probes how neurons respond to signals, changing in milliseconds! She's invented a way to inventory their RNA and proteins before and after firing. #neuroscience #RNA #RNAbiology #cellbiology #science #brain
