PIAS SUMO E3 ligases co-localize with and modulate SUMO modification of BRCA1, and are required for BRCA1 ubiquitin ligase activity in cells.

Morris等人发现，乳腺癌易感基因BRCA1（已知参与DNA损伤响应）产物的泛素连接酶活性，是在DNA损伤之后被由PIAS 调控的SUMO修饰激发的。

In vitro SUMO modification of the BRCA1/BARD1 heterodimer greatly increases its ligase activity, identifying it as a SUMO-regulated ubiquitin ligase. Further, PIAS SUMO ligases are required for complete accumulation of double-stranded DNA damage-repair proteins subsequent to RNF8 accrual, and for proficient double-strand break repair.

Galenty等人发现，两个连接酶（PIAS1 和 PIAS4）在DNA双链断裂处将各种不同的SUMO蛋白添加到DNA修复蛋白上，而SUMO蛋白则是泛素随后修饰这些蛋白中的其中一些所必需的。

The vertex within control mesh of fitting subdivision surface was located by iterative modification and local adaptive subdivision. This method makes it feasible to avoid the solution of linear equation system. The size of control mesh, which is corresponding to the fitting Loop subdivision surface, is smaller. The surface is reconstructed according to the given precision. It can represent detail characteristics of original model, and is piecewise smooth (C^2 continuous everywhere except at extraordinary vertices where they are C^1 continuous).

系统通过对控制网格顶点的循环修正和局部自适应细分来求解最终拟合细分曲面控制网格，避免了求解线性方程组，提高了拟合曲面的质量，实现了在给定精度下用较少的控制网格反映物体细节特征的分片光滑（片内除奇异点C^1，外其余C^2连续）的Loop细分曲面重建。
