RAB44 Knockout HEK293T Cells (RAB44基因敲除HEK293T细胞)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HEK293T细胞。本细胞中目的基因的敲除已经通过T7EI法的验证。本细胞株是多克隆细胞,可用于该目的基因的生物学功能研究,也可以用于该基因相应抗体的验证。
本HEK293T Cells为可同时表达Cas9、puromycin抗性基因和目的基因sgRNA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。制备本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。

本细胞中目的基因的敲除已经通过T7EI法的验证。
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。
本细胞用于实验时,建议同时选购无任何靶向的对照细胞Control Knockout HEK293T Cells (L00020)或靶向GFP的对照细胞GFP Knockout HEK293T Cells (L00022)。

Gene Summary | Rab44 is an atypical Rab GTPase that contains some additional domains such as the EF-hand and coiled-coil domains as well as Rab-GTPase domain. Rab44 was an upregulated protein during osteoclast differentiation. Knockdown of Rab44 by small interfering RNA promotes RANKL-induced osteoclast differentiation of the murine monocytic cell line, RAW-D or of bone marrow-derived macrophages (BMMs). In contrast, overexpression of Rab44 prevents osteoclast differentiation. Rab44 was localized in the Golgi complex and lysosomes, and Rab44 overexpression caused an enlargement of early endosomes. A series of deletion mutant studies of Rab44 showed that the coiled-coil domain and lipidation sites of Rab44 is important for regulation of osteoclast differentiation. Mechanistically, Rab44 affects nuclear factor of activated T-cells c1 (NFATc1) signaling in RANKL-stimulated macrophages. Moreover, Rab44 depletion caused an elevation in intracellular Ca2+ transients upon RANKL stimulation, and particularly regulated lysosomal Ca2+ influx. It was suggested that Rab44 negatively regulates osteoclast differentiation by modulating intracellular Ca2+ levels followed by NFATc1 activation. |
