I just noticed that researchers in the area of oncology often confuse Src kinases ( non-receptor tyrosine kinases that includes members such as Src, Yes, Fyn, and Fgr) with SRC kinases (steroid receptor co-activator, also known as nuclear receptor co-activator [NCOA], amplified in breast cancer 1 [AiB1] or thyroid hormone receptor activator molecule 1 [TRAM-1]).
The problem is that the sold SRC and Src kinases cause confusion in some labs. I noted that papers were published with arguing for the involvement of a steroid receptor co-activator kinase in the observed mechanism because it was sensitive to PPS. But PP2 is in fact a Sarc kinase inhbitor. :-)
Be careful with this in the future.
