Kwok E, Otto S, Khuu P, Carpenter A, Codding S, Reardon P, et al.
J Mol Biol . 2023 Jul; 435(17):168193. PMID: 37406927
Dysferlin is a large membrane protein found most prominently in striated muscle. Loss of dysferlin activity is associated with reduced exocytosis, abnormal intracellular Ca2+ and the muscle diseases limb-girdle muscular...

Carpenter A, Khuu P, Weidner T, Johnson C, Roeters S, Baio J
J Phys Chem B . 2023 Jan; 127(2):577-589. PMID: 36608331
Dysferlin is a 230 kD protein that plays a critical function in the active resealing of micron-sized injuries to the muscle sarcolemma by recruiting vesicles to patch the injured site...

Yan Q, Liu M, Kidarsa T, Johnson C, Loper J
Microorganisms . 2021 Aug; 9(7). PMID: 34361923
Antibiotic biosynthesis by microorganisms is commonly regulated through autoinduction, which allows producers to quickly amplify the production of antibiotics in response to environmental cues. Antibiotic autoinduction generally involves one pathway-specific...

Manchanda A, Bonventre J, Bugel S, Chatterjee P, Tanguay R, Johnson C
Mol Biol Cell . 2021 May; 32(14):1293-1305. PMID: 33979209
Release of neurotransmitter from sensory hair cells is regulated by otoferlin. Despite the importance of otoferlin in the auditory and vestibular pathways, the functional contributions of the domains of the...

Golbek T, Otto S, Roeters S, Weidner T, Johnson C, Baio J
J Phys Chem B . 2020 Dec; 125(1):148-157. PMID: 33355462
Mechanical stress on sarcolemma can create small tears in the muscle cell membrane. Within the sarcolemma resides the multidomain dysferlin protein. Mutations in this protein render it unable to repair...

Golbek T, Padmanarayana M, Roeters S, Weidner T, Johnson C, Baio J
Biophys J . 2019 Oct; 117(10):1820-1830. PMID: 31587832
Proteins that contain C2 domains are involved in a variety of biological processes, including encoding of sound, cell signaling, and cell membrane repair. Of particular importance is the interface activity...

Manchanda A, Chatterjee P, Bonventre J, Haggard D, Kindt K, Tanguay R, et al.
Sci Rep . 2019 Oct; 9(1):14273. PMID: 31582816
The protein otoferlin plays an essential role at the sensory hair cell synapse. Mutations in otoferlin result in deafness and depending on the species, mild to strong vestibular deficits. While...

Bonventre J, Holman C, Manchanda A, Codding S, Chau T, Huegel J, et al.
Mol Biol Cell . 2018 Dec; 30(3):293-301. PMID: 30516436
The precise spatial and temporal expression of genes is essential for proper organismal development. Despite their importance, however, many developmental genes have yet to be identified. We have determined that...

Johnson C
Biochemistry . 2017 Nov; 56(49):6413-6417. PMID: 29110470
The ferlin family proteins have emerged as multi-C2 domain regulators of calcium-triggered membrane fusion and fission events. While initially determined to share many of the features of members of the...

Hams N, Padmanarayana M, Qiu W, Johnson C
Proc Natl Acad Sci U S A . 2017 Jul; 114(30):8023-8028. PMID: 28696301
Sensory hair cells rely on otoferlin as the calcium sensor for exocytosis and encoding of sound preferentially over the neuronal calcium sensor synaptotagmin. Although it is established that synaptotagmin cannot...
