SAP 114 Activators

SAP114 Activators mainly function through altering phosphorylation cascades and influencing transcriptionalregulation. For instance, Anisomycin works by activating JNK, leading to the phosphorylation of downstream proteins in the JNK pathway, such as c-Jun. This activation process can enhance the transcription of genes that require splicing before translation, thus logically boosting SAP114 activity. Similarly, Etoposide, by inhibiting topoisomerase II, triggers a DNA damage response that can lead to increased transcription and subsequently, splicing activity, indirectly elevating SAP114 function.

Caffeine and Forskolin, on the other hand, increase intracellular cAMP levels, leading to the activation of PKA. The PKA activation results in an increased transcription of genes, which would necessitate splicing before being translated, thereby indirectly enhancing SAP114 activity. Numerous other SAP114 activators, such as Calyculin A, Staurosporine, Okadaic acid, PD98059, LY294002, SB203580, SP600125, and U0126, work by inhibiting protein phosphatases or kinases, altering phosphorylation cascades involved in transcription regulation. These alterations can potentially lead to an increase in the transcription of genes that require splicing before they are translated, indirectly amplifying the functional activity of SAP114.
