mPapaya Sequence

mPapaya was derived from mPapaya0.7 with the following mutations: Y168C
amino acid numbers relative to zFP538. show relative to mPapaya0.7

Note: Fig 2 and Fig S1 and Table S2 of Hoi (2013) erroneously show mPapaya0.7 (and therefore mPapaya1) with F99Y. The correct mutation is F97Y , as shown in the GenBank AGX93076 sequence (and Addgene mPapaya1 plasmids).

GenBank: AGX93076
IPG: 44320375
