重组蛋白质的可溶性鉴定：
1. 将按上法诱导培养后收集的菌体重悬于裂解液 1 (Lysis buffer under native conditions )中，然后在－80 oC 低温冰箱中放置 10 min。
2. 冰中解冻。
3. 在冰浴上用超声破碎仪破菌 6 次， 每次 10 sec，间歇 10 sec，电压 200-300 V。
4. 10000g，4oC，离心 20min，取上清（为溶液 A）， － 20 oC 保存； 另将沉淀用 同样裂解液 1 溶解（为溶液 B），同样 －20 oC 保存，供后继分析使用。
5. 将上述 A、B 溶液和诱导前后的细菌进行 SDS-PAGE 电泳， 考马斯亮蓝染色， 比较分析重组蛋白质的溶解性。如果诱导表达的蛋白质位于 A 溶液中， 则为可溶性蛋白；如果是在 B 溶液中，则为非可溶蛋白。

分子别名: Complement component 1 Q subcomponent-binding protein, mitochondrial,ASF/SF2-associated protein p32,Glycoprotein gC1qBP,C1qBP,Hyaluronan-binding protein 1,Mitochondrial matrix protein p32,gC1q-R protein,p33.
背景介绍: Hyaluronan binding protein 1 (HABP1), also known as p32 or gC1qR, is a ubiquitously expressed multifunctional phospho-protein implicated in cell signalling. Hyaluronan-binding protein 1 (HABP1) /p32/gC1qR was characterized as a highly acidic and oligomeric protein, which binds to different ligands like hyaluronan, C1q, and mannosylated albumin. The role of hyaluronan binding protein 1 (HABP1) in cell signaling was investigated and in vitro. HABP1 overexpressing cells showed extensive vacuolation and reduced growth rate, which was corrected by frequent medium replenishment. Further investigation revealed that HABP1 overexpressing cells undergo apoptosis, and they failed to enter into the S-phase. The sperm surface HABP1 level can be correlated with the degree of sperm motility.Hyaluronan binding protein 1 (HABP1) was reported to be present on human sperm surface and its involvement in fertilization has already been elucidated: decreased HABP1 level may be associated with low motility of sperms, which in turn might cause infertility in the patient. HABP1 also is an endogenous substrate for MAP kinase and upon mitogenic stimulation it is translocated to the nucleus in a MAP kinase-dependent manner.
