CREATE TABLE table_28971 ("Species" CLOB, "Common Name" CLOB, "Protein Name" CLOB, "Accession Number" CLOB, "NT Length" CLOB, "NT Identity" CLOB, "AA Length" CLOB, "AA Identity" CLOB, "E-Value" CLOB)

What is the aa length when the protein name is c11orf73?
SELECT "AA Length" FROM table_28971 WHERE "Protein Name" = 'C11orf73'
SELECT "AA Length" FROM "table_28971" WHERE "Protein Name" = 'C11orf73'
