RPL20B

Symbol: RPL20B
Name: Ribosomal Protein of the Large subunit 20B
Alias: RPL18A1;L18B;L20B
Entrez gene ID: 854489
Ensembl gene ID: YOR312C
Species: Yeast (Taxid: 4932)

Functional description:
Rpl20bp; Protein component of the large (60S) ribosomal subunit, nearly identical to Rpl20Ap and has similarity to rat L18a ribosomal protein [Source:SGD;Acc:S000005839] [Ensembl]

Observation:

Deletion of RPL20B increases mean replicative lifespan by 35 - 50% [19030232] to 40 - 50% [18423200] in the alpha and a strains. While deletion of RPL20B non-significantly increases mean replicative lifespan by 3% in the ORF collection, it significantly by 36% the remade strain [22377630].

RPL20b deletion extends mean, median and maximum lifespan by 71, 89 and 82%, respectively [23167605].

Lifespan extension by RPL20B deletion is Hac1, Sir2 and Fob1 independent, but requires Gcn4 [18423200; 21902802].
