在NCBI上怎么查特定物种的某一酶的蛋白质序列

直接在NCBI主页输入你要找的基因的名字,比如S1PR1,然后搜索,找到下面的内容：Genes90Gene:collectedinformationaboutgeneloci1HomoloGene:homologousgenesetsforselectedorganisms12UniGene:clustersofexpressedtranscripts点90进去,里面是NCBI上这个基因在不同物种中的所有序列,找到是链霉菌这个物种就ok,我如果找人的话,就应该是：S1PR1–sphingosine-1-phosphatereceptor1[Homosapiens(human)]然后再点进去GenomicNG_016181.1RefSeqGeneRange5001..9772DownloadGenBank,FASTA,SequenceViewer(Graphics)mRNAandProtein(s)NM_001400.4→NP_001391.2sphingosine1-phosphatereceptor1SeeproteinsidenticaltoNP_001391.2Status:REVIEWEDpfam00001Location:68–311BlastScore:3677tm_1;7transmembranereceptor(rhodopsinfamily)Sourcesequence(s)BC018650,CR977007,DB132417,DB572979ConsensusCDSCCDS777.1UniProtKB/Swiss-ProtP21453RelatedENSP00000305416,OTTHUMP00000012525,ENST00000305352,OTTHUMT00000029908ConservedDomains(1)summaryGenBank和FASTA可以查看它在基因组上的序列NM_001400.4和NP_001391.2分别是其mRNA序列和蛋白质序列祝好!
