Medium	Parameter	Value for:
		Wild type	apm3 mutant	lvsB mutant
HL5	No. of PLsa	2.54 ± 0.03	2.26 ± 0.04	1.35 ± 0.13

^aAverage number of PLs per cell ± SEM (n = 3).

^bPercentage of cells presenting a p80 patch.

^cThe fusion efficacy (a.u.) was calculated by dividing the frequency of p80 patches by the number of PLs.
