Sld3 is conserved in yeast and fungi, and treslin, also known as Ticrr, has been identified as the functional counterpart of Sld3 in metazoans. Yeast Sld3 and its metazoan counterpart treslin are the hub proteins mediating protein associations critical for formation of the helicase. This entry represents the N-terminal domain of Sld3 which is shown to bind to the N-terminal domain of Sld7 [1].
