TIAM2

TIAM2, also known as T-lymphoma invasion and metastasis-inducing protein 2, is a key member of the TIAM family of guanine nucleotide exchange factors (GEFs). Primarily located in the cytoplasm, TIAM2 is essential for regulating cellular processes, especially those involving cytoskeletal dynamics, cell migration, and invasion. A defining feature of TIAM2 is its role as a molecular switch for activating Rho GTPases, particularly Rac1. Through its GEF activity, TIAM2 facilitates the exchange of GDP for GTP on Rac1, triggering downstream signalling pathways that control actin cytoskeleton rearrangements.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
