CHRNA1 Protein, Human (His)

The CHRNA1 Protein undergoes a substantial conformational shift upon acetylcholine binding, influencing all subunits and leading to the activation of an ion-conducting channel. Yet, the acetylcholine receptor alpha subunit of CHRNA1 can be non-functional in certain cases, underscoring the need to comprehend the factors governing its functionality and integration into fully operational acetylcholine-gated cation-selective channels. CHRNA1 Protein, Human (His) is the recombinant human-derived CHRNA1 protein, expressed by E. coli , with N-6*His labeled tag. The total length of CHRNA1 Protein, Human (His) is 235 a.a., with molecular weight of ~31.1 kDa.

Upon binding with acetylcholine, the CHRNA1 protein undergoes a significant conformational shift that impacts all subunits, resulting in the opening of an ion-conducting channel across the plasma membrane. However, in some instances, the acetylcholine receptor alpha subunit of CHRNA1 may be non-functional and not integrated into fully operational acetylcholine-gated cation-selective channels, emphasizing the importance of understanding the factors that regulate its functionality and incorporation into the functional receptor complex.
