Does Coinbase support GBP?

Excuse me, I was wondering if I could get some clarification on Coinbase's support for a specific currency. Specifically, does Coinbase support transactions in British Pounds Sterling (GBP)? I'm interested in knowing if I can use my GBP to buy, sell, or trade cryptocurrencies on the platform without having to convert to another currency first. It would be greatly appreciated if you could provide me with a definitive answer to this question.
