Denha S, DeLaet N, Abukamil A, Alexopoulos A, Keller A, Atang A, et al.
bioRxiv . 2024 Sep; PMID: 39345584
Spinocerebellar ataxia type 5 (SCA5) mutations in the protein β-III-spectrin cluster to the N-terminal actin-binding domain (ABD) and the central spectrin-repeat domains (SRDs). We previously reported that a common molecular...

Cells . 2023 Aug; 12(16). PMID: 37626910
Spinocerebellar ataxia type 5 (SCA5) is a neurodegenerative disease caused by mutations in the gene encoding the cytoskeletal protein β-III-spectrin. Previously, we demonstrated that a L253P missense mutation, localizing to...

Spinocerebellar ataxia type 5 (SCA5) is a neurodegenerative disease caused by mutations in the SPTBN2 gene encoding the cytoskeletal protein β-III-spectrin. Previously, we demonstrated that a L253P missense mutation, localizing...

Guhathakurta P, Rebbeck R, Denha S, Keller A, Carter A, Atang A, et al.
J Biol Chem . 2023 Feb; 299(3):102956. PMID: 36731793
β-III-Spectrin is a key cytoskeletal protein that localizes to the soma and dendrites of cerebellar Purkinje cells and is required for dendritic arborization and signaling. A spinocerebellar ataxia type 5...

Denha S, Atang A, Hays T, Avery A
Sci Rep . 2022 Feb; 12(1):1726. PMID: 35110634
Recent structural studies of β-III-spectrin and related cytoskeletal proteins revealed N-terminal sequences that directly bind actin. These sequences are variable in structure, and immediately precede a conserved actin-binding domain composed...

Rebbeck R, Andrick A, Denha S, Svensson B, Guhathakurta P, Thomas D, et al.
J Biol Chem . 2021 Apr; 296:100215. PMID: 33839680
Numerous diseases are linked to mutations in the actin-binding domains (ABDs) of conserved cytoskeletal proteins, including β-III-spectrin, α-actinin, filamin, and dystrophin. A β-III-spectrin ABD mutation (L253P) linked to spinocerebellar ataxia...
