Can I transfer from Coinbase to Uniswap?

Could you please elaborate on whether it's feasible to transfer funds from Coinbase to Uniswap? I'm interested in exploring the DeFi ecosystem but am unsure about the specific steps required for this type of transaction. Are there any specific cryptocurrencies or tokens that are supported for this transfer? Additionally, are there any fees or limitations I should be aware of? I'd appreciate any detailed guidance you can provide on this matter. Thank you in advance for your assistance.
