Switch #:
SWTI000556
Switch type:
Binary
Switch subtype:
Pre-translational

Description:
Alternative splicing removes the TRAF2-binding motif of Ubiquitin carboxyl-terminal hydrolase CYLD (Cyld), abrogating binding to TNF receptor-associated factor 2 (Traf2). Mice expressing solely the alternatively spliced Isoform 3 of Ubiquitin carboxyl-terminal hydrolase CYLD (Cyld) (sCYLD) show an altered B-cell expansion profile and have more stable NF-kB proteins.

Participants:
(1) Ubiquitin carboxyl-terminal hydrolase CYLD (Cyld)
(2) TNF receptor-associated factor 2 (Traf2)

Interactions
Interaction #1 Cyld - Traf2

Interfaces
(1) ELM:LIG_TRAF2_3 motif (449PVQES453) in Ubiquitin carboxyl-terminal hydrolase CYLD (Cyld)
(2) MATH domain (358-498) in TNF receptor-associated factor 2 (Traf2)
