[Kramer JM] zmp for Zinc MetalloProtease. cg115 is deletion derivative of pk205tci, no apparent phenotype. Overexpression of zmp-1 leads to abnormality, degradation of extracellular matrix components. cDNAs map to C28H8/EGAP1. Encodes predicted protein related to matrix metalloproteases.
zmp-1 encodes a zinc matrix metalloproteinase that enables anchor cell (AC) invasion during postembryonic vulval development; ZMP-1's proteinase activity has been confirmed in vitro; N-terminus to C-terminus, ZMP-1 is predicted to have a signal sequence, peptidoglycan-binding domain, a central matrix protease domain, a coiled-coil domain, and four hemopexin domains; ZMP-1 is expressed in AC during larval development, vulD and vulE in larvae and adults, and vulA in young adults onward; ZMP-1 is expressed in AC at the time it invades the basement membrane (L3 larval stage), and is localized to puncta often concentrated at the invasive basolateral membrane; ZMP-1::GFP diffuses from AC to utse cytoplasm upon fusion of these cells; ZMP-1 expression in AC requires EGL-43 (perhaps directly), and FOS-1A (indirectly); transcription of zmp-1 in AC, vulA, and vulE is driven by physically distinct sites in the zmp-1 5' flanking sequence; other regulators of ZMP-1 expression in other cell types include COG-1, EGL-38, LIN-11, LIN-29, and NHR-67; zmp-1(cg115) and zmp-1(RNAi) animals have no grossly obvious phenotypes, but null zmp-1(cg115) mutations enhance a subtle defect of AC invasion seen with null cdh-3(pk87) or him-4(rh319) mutations.
Enables metallopeptidase activity. Involved in basement membrane disassembly. Located in cell surface. Expressed in several structures, including P6.paal; P6.paar; P6.papl; gonad; and vulval cell. Human ortholog(s) of this gene implicated in prostate cancer and transitional cell carcinoma. Is an ortholog of human MMP15 (matrix metallopeptidase 15) and MMP24 (matrix metallopeptidase 24).
C28H8 and EGAP borders : found metalloprotease blastX matches and made gene corresponding to zmp-1,[sdm 000904]
Sequence correction updated to EGAP1.3 from EGAP1.2 (this may have been an error) [krb 020717]
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
