DCLK3 Knockout HEK293T Trizol Lysate (DCLK3基因敲除HEK293T细胞Trizol裂解液)是通过同时表达Cas9、目的基因sgRNA和puromycin抗性基因，并实现了目的基因CRISPR敲除的多克隆HEK293T细胞的Trizol裂解液。该细胞中目的基因的敲除已经通过T7EI法的验证。本产品可用于该目的基因敲除后其信号通路相关RNA表达的研究。
本Trizol裂解液源于可同时表达Cas9、目的基因sgRNA和puromycin抗性基因的慢病毒感染HEK293T细胞并经过puromycin筛选后获得的多克隆HEK293T细胞。制备该细胞的相应慢病毒的基因序列的关键图谱信息请参考图1。

由于本细胞是通过CRISPR/Cas9技术获得的多克隆细胞，基于CRISPR/Cas9技术的特点，理论上平均有2/3的细胞发生移码突变而导致了目的基因的敲除，平均有1/3的细胞并未发生移码突变。很多情况下有约2/3的细胞发生目的基因的敲除，已经足以进行很多的目的基因的生物学功能的研究了。如果希望获得100%基因敲除的细胞，可以自行使用本产品筛选单克隆细胞，或者委托碧云天进行单克隆细胞株的筛选服务。
本Trizol裂解液用于实验时，建议同时选购无任何靶向的对照细胞Trizol裂解液Control Knockout HEK293T Trizol Lysate (L00031)或靶向GFP的对照Trizol裂解液GFP Knockout HEK293T Trizol Lysate (L00033)。

| Gene Summary | DCLK3 is the third member of the doublecortin-like kinase (DCLK) family. The DCLK1/2 proteins have a conserved C-terminal ‘serine/threonine kinase’ domain similar to that of Ca2+/calmodulin kinase IV (CaMKIV) and an N-terminal putative doublecortin (DCX) domain mediating their anchorage to microtubules. DCLK1 and DCLK2 are involved in neural development and the maturation of neuronal architecture, including the organization of dendritic spines in particular and play an important role in axonal regeneration mainly through their DCX domain. DCLK3 functions are likely not similar to those of DCLK1/2. The putative DCX domain in the N-terminal part of DCLK1/2 is not present in DCLK3. In addition, DCLK1 and DCLK2 have only 56–54% identities in the amino acid primary sequence of DCLK3, with differences in and around the kinase domain in the C-terminal part of the proteins. DCLK3 displays a more neuron-specific pattern of expression than DCLK1/2, which are also expressed in astrocytes. DCLK3 is mainly expressed in the adult and not in the developing forebrain. DCLK3 was as an oncogenic factor in colorectal cancer. High expression of DCLK3 (resulting from at-distance effects of a single polymorphism in the promoter of the MLH1 gene) in cancer cells was shown to be associated with increased malignancy. This suggested that DCLK3 has biological functions that may modulate cell survival. The kinase activity of DCLK3 could impact striatal neurons. |
