TIGD2 (Tigger Transposable Element Derived 2) is a nuclear protein containing HMG-box domains, belonging to a family of DNA-binding proteins derived from transposable elements. While its precise biological functions are not fully characterized, TIGD2 is implicated in DNA organization and chromatin remodeling.
TIGD2 is a member of the "Tigger" subfamily of HMG-box containing proteins, named after the Tigger DNA transposon. These proteins have been co-opted during evolution to serve various cellular functions, particularly in DNA metabolism and gene regulation.
