| 描述: | Catalytic subunit of the DNA primase complex and component of the DNA polymerase alpha complex (also known as the alpha DNA polymerase-primase complex) which play an essential role in the initiation of DNA synthesis (PubMed:8026492, PubMed:8253737). During the S phase of the cell cycle, the DNA polymerase alpha complex (composed of a catalytic subunit POLA1, an accessory subunit POLA2 and two primase subunits, the catalytic subunit PRIM1 and the regulatory subunit PRIM2) is recruited to DNA at the replicative forks via direct interactions with MCM10 and WDHD1 (By similarity). The primase subunit of the polymerase alpha complex initiates DNA synthesis by oligomerising short RNA primers on both leading and lagging strands. These primers are initially extended by the polymerase alpha catalytic subunit and subsequently transferred to polymerase delta and polymerase epsilon for processive synthesis on the lagging and leading strand, respectively (By similarity). In the primase complex, both subunits are necessary for the initial di-nucleotide formation, but the extension of the primer depends only on the catalytic subunit (PubMed:8253737). Can add both ribo- and deoxynucleotides during elongation of the primers (PubMed:8253737). Synthesizes 9-mer RNA primers (also known as the 'unit length' RNA primers) (By similarity). Incorporates only ribonucleotides in the presence of ribo- and deoxy-nucleotide triphosphates (rNTPs, dNTPs). Requires template thymine or cytidine to start the RNA primer synthesis, with an adenine or guanine at its 5'-end (By similarity). Binds single stranded DNA (PubMed:8253737). {ECO:0000250|UniProtKB:P09884, ECO:0000250|UniProtKB:P49642, ECO:0000269|PubMed:8026492, ECO:0000269|PubMed:8253737}. |

| 复溶: |
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles. 收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底,如果粉末浮起,开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL(请注意蛋白复溶浓度不能低于0.1 mg/mL),室温平衡5-10 min保证充分溶解,复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存,建议复溶时添加载体蛋白或者稳定剂(如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖),同时将复溶后的蛋白溶液按照需求进行分装,储存于-20°C至-80°C,随取随用,避免反复冻融。 |
| 储存: |
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week. 未开盖的干粉蛋白在 -20°C至-80°C可保存12个月; 复溶之后,蛋白溶液在-20°C及以下可保存3个月,在2-8℃可保存1周。 |
