Eritrocitni membranski protein band 4.1 (EPB41) je multifunkcioni protein koji posreduje interakcije između eritrocitnog citoskeletona i okružujuće ćelijske membrane. Ovaj protein je visoko zastupljen u neuronima. On je strukturno sličan sa EPB41. EPB41L1 se vezuje za i stabilizuje D2 i D3 dopaminske receptore u neuronskoj ćelijskoj membrani. Višestruke transkriptne varijante kodiraju različite izoforme. Do sada su dve izoforme ispitane.[3]

Interakcije uredi

Poznato je da EPB41L1 formira interakcije sa ITPR1,[4] dopaminskim receptorom D2,[5] dopaminskim receptorom D3,[5] CENTG1[6] i proteinom 1 nukleusnog mitotičkog aparata.[7]
