Pera T, Penn RB. Methods to Investigate β-Arrestin-Mediated Regulation of GPCR Function in Human Airway Smooth Muscle.  Methods Mol Biol. 2019;1957:69-82. doi: 10.1007/978-1-4939-9158-7_4. PMID: 30919347

This paper details methods for studying the role of arrestins in regulating GPCR functions in airway smooth muscle cells.

Pera T, Tompkins E, Katz M, Wang B, Deshpande DA, Weinman EJ, Penn RB. Specificity of NHERF1 regulation of GPCR signaling and function in human airway smooth muscle. FASEB J. 2019 Aug;33(8):9008-9016. doi: 10.1096/fj.201900323R. Epub 2019 May 1. PMID: 31042404

This paper reveals NHERF1 acts as an adapter to compartmentalize cAMP signaling in airway smooth muscle.

Pera T, Deshpande DA, Ippolito M, Wang B, Gavrila A, Michael JV, Nayak AP, Tompkins E, Farrell E, Kroeze WK, Roth BL, Panettieri RA Jr, Benovic JL, An SS, Dulin NO, Penn RB. Biased signaling of the proton-sensing receptor OGR1 by benzodiazepines. FASEB J. 2018 Feb;32(2):862-874. PMID: 29042451

This is the first paper to identify small molecule ligands for the proton-sensing receptor OGR1 and determine the capacity of ligands to selectively bias signaling towards Gs pathways but not Gq pathways.

Pera T, Hegde A, Deshpande DA, Morgan SJ, Tiegs BC, Theriot BS, Choi YH, Walker JK, Penn RB. Specificity of arrestin subtypes in regulating airway smooth muscle G protein-coupled receptor signaling and function. FASEB J. 2015 Oct;29(10):4227-35. PMID: 26103985

This paper details how arrestins differentially regulate muscarinic and adrenergic receptor signaling in airway smooth muscle to affect contraction and relaxation.
