The function of Ensembl gene identifier ENSG00000078369 (GNB1, G protein subunit beta 1) is as follows. Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems (PubMed:29925951, PubMed:33762731, PubMed:34239069, PubMed:35610220, PubMed:35714614, PubMed:35835867, PubMed:36087581, PubMed:36989299, PubMed:37327704, PubMed:37935376, PubMed:37935377, PubMed:37963465, PubMed:37991948, PubMed:38168118, PubMed:38552625, PubMed:39103320). The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction (PubMed:29925951, PubMed:33762731, PubMed:34239069, PubMed:35610220, PubMed:35714614, PubMed:35835867, PubMed:36087581, PubMed:36989299, PubMed:37327704, PubMed:37935376, PubMed:37935377, PubMed:37963465, PubMed:38168118, PubMed:38552625, PubMed:39103320). {ECO:0000269|PubMed:29925951, ECO:0000269|PubMed:33762731, ECO:0000269|PubMed:34239069, ECO:0000269|PubMed:35610220, ECO:0000269|PubMed:35714614, ECO:0000269|PubMed:35835867, ECO:0000269|PubMed:36087581, ECO:0000269|PubMed:36989299, ECO:0000269|PubMed:37327704, ECO:0000269|PubMed:37935376, ECO:0000269|PubMed:37935377, ECO:0000269|PubMed:37963465, ECO:0000269|PubMed:37991948, ECO:0000269|PubMed:38168118, ECO:0000269|PubMed:38552625, ECO:0000269|PubMed:39103320}.
