Ab Minor 7, written Abm7, is built from Ab, Cb, Eb and Gb: the root, minor 3rd, 5th and minor 7th.
Its 3rd and 7th, Cb and Gb, are its guide tones: they say what kind of chord it is, so voicings are built around them and the root is often left to the bass.
In the progressions here, Abm7 is the ii7 of the Major ii-V Progression in Gb, the iv7 of the Backdoor ii-V-I Progression in Eb, the i7 of the Minor i-vi-ii-V Progression in Ab, the v7 of the Whole-Step ii-V Chain in Db, the ♭iii7 of the Half-Step ii-V Chain in F and the ♭ii7 of the Modal AABA in G.
