Transcription factors are not only about activation&#8212;helping things move, grow, and express. Many are. But some are regulatory, some are inhibitory. They tune or even block transcription. They say &#8220;not yet&#8221; or &#8220;not this way.&#8221; It is natural to see this as a negative. As a block, as something in the way.</p><p>But inhibition isn&#8217;t always obstruction. Sometimes it&#8217;s <strong>protection.</strong></p><p>Sometimes the people who stop us, who make us pause, who say <em>&#8220;wait&#8212;are you sure?&#8221;</em> aren&#8217;t blocking our path. They&#8217;re keeping us from walking off a cliff we couldn&#8217;t see yet.</p><p>The trick is to learn which is which and staying open to all the messages and all kinds of help.</p><div class="captioned-button-wrap" data-attrs="{&quot;url&quot;:&quot;https://www.christinapressl.com/p/transcription-factors-the-people?utm_source=substack&utm_medium=email&utm_content=share&action=share&quot;,&quot;text&quot;:&quot;Share&quot;}" data-component-name="CaptionedButtonToDOM"><div class="preamble"><p class="cta-caption"><em>Sometimes we need someone to help us pause.
