XX SF can interact simultaneously with Tat and CDK9 on TAR RNA in vitro [4]; SF the cyclin domain is necessary and sufficient to interact with Tat and promote cooperative binding to TAR RNA in vitro, as well as mediate Tat transactivation in vivo [4]; SF the interaction with Tat requires zinc as well as essential cysteine residues in both proteins (e.g. C261 in human cyclinT1, compare murine cyclinT1 T02732) [4]; XX CP ubiquitous (heart, brain, placenta, lung, liver, skeletal muscle, kidney, pancreas) [1]. XX FF human cyclinT1 (but not mouse cyclinT1 or human cyclins T2a or T2b) could support interaction between Tat and TAR in vitro and could rescue Tat activity in nonpermissive rodent cells [2] [3] [4]; XX IN T05109 53BP1; human, Homo sapiens.
