G protein subunit alpha L (GαL)

"G protein subunit alpha L" is not a standard, widely recognized name for any human G protein alpha subunit. Heterotrimeric G proteins consist of alpha, beta, and gamma subunits, with the alpha subunit playing a central role in GDP/GTP binding and hydrolysis and determining G protein class and signaling specificity. Major alpha subunit subfamilies include Gαs, Gαi/o, Gαq/11, and Gα12/13, each encoded by distinct genes. The subclass "L" does not match these canonical classifications, and no major databases or reviews identify a "G protein subunit alpha L" as a separate entity. This suggests the term is either a misnomer, transcription/translation error, or an extremely rare/obsolete alias for another alpha subunit, potentially GNAI3 (Gαi3), although this is not definitive. Therefore, "G protein subunit alpha L" should be considered ambiguous or incorrect for structured biomedical curation.
