She also said she was pained at the "politicisation of Amma's death."
Sasikala said that she was looking for an "explanation" why Governor Ch Vidyasagar Rao refused to give her an audience despite many requests.
"We tried to meet him, but was told that the Governor is in Ooty. I hope the Governor protects the Constitution and upholds the dignity of law," she said in an interview to CNN-News18 TV channel.
Attacking Panneerselvam, whom she called a "traitor", she alleged that his act was a betrayal to Amma and claimed that his actions in the assembly were "suspicious."
She alleged that the opposition DMK is now looking at Panneerselvam as one of their own.
Earlier, Panneerselvam had ordered a probe into what he said were doubts regarding the death of Jayalalithaa, which would be headed by a retired High Court judge. He had also accused Sasikala of not allowing him to meet the late Chief Minister when she was hospitalised for over 70 days.
The AIADMK leader said that she was not a bit worried about a probe but it is sad that Jayalalithaa's death was being politicised.
Sasikala also rubbished Panneerselvam's claim that he was
threatened and forced to resign as Chief Minister.
"There is no truth in his claim that he was threatened by us. He proposed me to take over as General Secretary of the party. Somebody is behind this. I think all this is politically motivated," she claimed.
Refusing to be drawn into a debate over this aspect, she only said "we have faxed a letter to the Governor. We have sent a letter again to him to remind him about our request. They gave an acknowledgement, but that's it," she told the channel.
Sasikala also targetted rival party DMK alleging it may have had a role in instigating Panneerselvam to rebel.
"DMK must be behind Panneerselvam's recent activities," she said. DMK President M K Stalin, has vehemently denied his party has had anything to do with it.
