General annotation
TypeCDS
FunctionInvolved in signal transduction (via phosphorylation). Thought to be involved in cell division/differentiation [catalytic activity: ATP + a protein = ADP + a phosphoprotein].
ProductProbable transmembrane serine/threonine-protein kinase I PknI (protein kinase I) (STPK I) (phosphorylase B kinase kinase) (hydroxyalkyl-protein kinase)
CommentsRv2914c, (MTCY338.02c), len: 585 aa. Probable pknI, transmembrane serine/threonine-protein kinase (see citation below), ala-rich protein, highly similar to many in Mycobacterium tuberculosis and other bacteria e.g. Q9RLQ7|MBK putative serine/threonine protein kinase from Mycobacterium bovis BCG (291 aa), FASTA scores: opt: 376, E(): 1.1e-10, (36.95% identity in 287 aa overlap); P33973|PKN1_MYXXA serine/threonine-protein kinase from Myxococcus xanthus (693 aa), FASTA scores: opt: 286, E(): 5.4e-10, (29.9% identity in 374 aa overlap); P72003|PKNF_MYCTU|Rv1746|MT1788|MTCY28.09 probable serine/threonine-protein kinase from Mycobacterium tuberculosis (476 aa), FASTA scores: opt: 675, E(): 1.7e-24, (39.75% identity in 468 aa overlap); Q10697|PKNJ_MYCTU|Rv2088|MT2149|MTCY49.28 probable serine/threonine-protein kinase from Mycobacterium tuberculosis (589 aa), FASTA scores: opt: 574, E(): 1e-19, (34.85% identity in 479 aa overlap); etc. Equivalent to AAK47308 from Mycobacterium tuberculosis strain CDC1551 (603 aa) but shorter 18 aa. Contains Hank's kinase subdomain. Belongs to the Ser/Thr family of protein kinases.
Functional categoryRegulatory proteins
ProteomicsIdentified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar et al., 2011).
MutantNon-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, but essential for in vitro growth on cholesterol; by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). M. tuberculosis H37Rv pknI|Rv2914c mutant shows increased growth in THP-1 cells compared to wild-type; SCID mice infected with wild-type survive longer than those infected with mutant (See Gopalaswamy et al., 2009).
