MMP10

MMP10 (stromelysin-2, transin-2; UniProt P09238, 11q22.2) is a secreted human matrix metalloproteinase degrading fibronectin, laminin, and collagens III-V, expressed in keratinocytes and macrophages, active in wound healing, immunity, and cancer, and distinct from its closest relative MMP3.

MMP12

MMP12 (macrophage metalloelastase, MMP-12, EC 3.4.24.65) is a human chromosome 11q22.2 gene encoding a zinc-dependent matrix metalloproteinase from macrophages that degrades elastin; linked to COPD, asthma, atherosclerosis, and aneurysm.

MMP14

MMP14 (MT1-MMP, matrix metallopeptidase 14) is a type I transmembrane zinc endopeptidase, the first membrane-type MMP (1994), that activates proMMP2 via TIMP2, degrades collagens, sheds CD44, and drives cancer invasion; T17R mutation causes Winchester syndrome.

MMP2

MMP2, also called gelatinase A or 72-kDa type IV collagenase, is a zinc-dependent matrix metalloproteinase degrading type IV/V collagen, fibronectin, laminin, and elastin; uniquely activated at the cell surface by MT1-MMP with TIMP-2, and linked to cancer, cardiovascular, and diabetic disease.

MMP3

MMP3 (stromelysin-1, MMP-3), gene at 11q22.2, encodes a secreted zinc endopeptidase degrading fibronectin, laminin, collagens III/IV/IX/X, and proteoglycans; activates MMP-1 and MMP-9; implicated in arthritis, cancer, fibrosis, and bone.

MMP8

MMP8 (matrix metallopeptidase 8, neutrophil collagenase, MMP-8, EC 3.4.24.34) is a human chromosome 11q22.3 gene encoding a zinc-dependent collagenase stored in neutrophil granules, degrading type I, II, III collagens and serving as a periodontitis biomarker.

MMP9

MMP9 (MMP-9, gelatinase B, 92 kDa type IV collagenase) is a zinc-dependent secreted endopeptidase degrading type IV/V collagen, key to leukocyte migration, inflammation, cancer metastasis, and a difficult drug target; only doxycycline is approved among MMP inhibitors.

MMR vaccine

MMR vaccine: live attenuated combination vaccine against measles, mumps, rubella; two doses at 12–15 months and 4–6 years; 93–97% effective; contraindicated in pregnancy; no autism link.

MMRTG

The Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) is a nuclear battery that converts plutonium-238 decay heat into electricity, powering NASA's Curiosity and Perseverance rovers on Mars and planned for the Dragonfly mission to Titan.

MMS (Massively Multilingual Speech)

Massively Multilingual Speech (MMS) is a set of open speech models released by Meta AI in May 2023, extending speech recognition and synthesis to over 1,100 languages.

MMSE equalization

MMSE equalization, short for minimum mean square error, is a linear equalization method that minimizes the error between the equalizer output and the transmitted symbol, balancing noise against residual interference.

MMST

MMST is a word stamped on the royal storage-jar handles of Hezekiah, king of Judah, in the late eighth century BCE, and scholars still dispute its meaning.

Mmusi Maimane

Mmusi Aloysias Maimane (born 1980) is a South African politician, former Democratic Alliance leader 2015–2019, first black leader of the DA, and founder and leader of Build One South Africa (BOSA), now an MP and committee chairperson.

MMW Fortschritte der Medizin

MMW Fortschritte der Medizin is a German-language medical journal published by Springer Medizin, formed in 1999 from the merger of the Münchener Medizinische Wochenschrift and Fortschritte der Medizin.

MMX (spacecraft)

MMX (Martian Moons eXploration) is a JAXA spacecraft that will land on Mars's moon Phobos and return more than 10 grams of samples to Earth in 2031.

MMX rover

The MMX rover, named Idefix, is a four-wheeled rover built by CNES and DLR for JAXA's MMX mission, to explore the Martian moon Phobos for about 100 days.
