Hsp70 promoter sequences drive expression of U2A.
increased cell number | temperature conditional, with U2A1.W
male sterile | temperature conditional, with U2A1.W
spermatocyte cyst | temperature conditional, with U2A1.W
spermatogonium | temperature conditional, with U2A1.W
spermatozoon | temperature conditional, with U2A1.W
U2Ahs.PW rescues U2A1.W
Continuous heat shock treatment with U2Ahs.PW rescues lethality of U2A1.W/U2A1.W, allowing survival to adulthood.
